Plotting discrete count data as “staple” of points in ggplot2
You could do this, but it requires a bit of manual tuning of the scale to look decent. plot.df <- data.frame(band = rep(bands, count), count = unlist(lapply(count, seq_len))) ggplot(plot.df, aes(x = count, y=band)) + geom_point() + scale_x_continuous(limits=c(0, 10), breaks=seq(0, 10, by=2) ...
Plotting (ggplot) numeric values from mixed long format column of class character
As mentioned by @Spacedman, you example is not reproducible/consistent. Part 1 This works: filter(mydata, measure == "pagesubmit") %>% ggplot(aes( y = as.numeric(value), x = as.factor(subject_instance), color = as.factor(subject_instance))) + geom_boxplot() Part 2 If you want the mean of all measure equal to pagesubmit, you can do: filter(mydata, measure == "pagesubmit")...
splitting or removing graphs after arrangeGrob
First, use grid.ls() to see a listing of the grobs that make up the plot. Here, you'll be looking for the names of the two gTree objects that encode the individual plots. (Compared to lattice, ggplot2's naming of component grobs is relatively unhelpful, although in this case, it's not too...
qplot - legend text in italics
Try sth like that p + theme(legend.text = element_text(face = "italic")) ...
How to make a Pareto chart (aka rank-order chart) with ggplot2
There's some good discussion here about why plotting with two different y-axes is a bad idea. I'll limit to plotting the sales and cumulative percentage separately and displaying them next to each other to give the full visual representation of the Pareto chart. # Sales df <- data.frame(country, sales) df...
how to get x axis to intercept y at non-zero position with ggplot2?
You just have to hack the scale labels. library(ggplot2) # fake data my_dat <- data.frame(x=1:(24*3), temp=sample(0:100, 24*3)) # the initial plot ggplot(my_dat, aes(x=x, y=temp, fill=temp)) + geom_bar(stat='identity') # make a copy my_dat2 <- my_dat # pretend that 50 is zero my_dat2$temp <- my_dat2$temp-50 ggplot(my_dat2, aes(x=x, y=temp, fill=temp)) + geom_bar(stat='identity') +...
Error with facet_wrap since updating ggplot2 to 1.0.1
The warning includes In loop_apply(n, do.ply), which indicates that package plyr might be involved in whatever is going on. When I loaded package plyr_1.8.2 I could reproduce the error. Updating to the current development version, plyr_1.8.2.9000, solves this issue....
Subgroup Boxplots in R
Is this close to what you had in mind? There's a boxplot for each value of peer for each year. I've also included the mean values for each group. # Boxplots for each combination of year and peer, with means superimposed ggplot(dat, aes(year, pct, group=interaction(year,peer), colour=factor(peer))) + geom_boxplot(position=position_dodge(width=0.4), width=0.4) +...
R Biplot with clusters as colors
I think you should try theme(legend.position="none"). library(factoextra) plot(fviz_pca_biplot(pca, label="var", habillage=as.factor(kc$cluster)) + ggtitle("") + theme(text = element_text(size = 15), panel.background = element_blank(), panel.grid.major = element_blank(), panel.grid.minor = element_blank(), axis.line = element_line(colour = "black"), legend.position="none")) This is what I get: ...
Sequence index plots in ggplot2 using geom_tile( )
Two small changes: mvad_long$id <- as.factor(mvad_long$id) ggplot(data=mvad_long,aes(x=Month,y=id,fill=state))+ geom_tile()+facet_wrap(~cluster,scales = "free_y") ggplot was treating id as a numerical variable, rather than a factor, and then the scales were fixed....
Setting limits with scale_x_datetime and time data
the error message says that you should use as.POSIXct on lims. You also need to add the date (year, month and day) in lims, because by default it will be `2015, which is off limits. lims <- as.POSIXct(strptime(c("2011-01-01 03:00","2011-01-01 16:00"), format = "%Y-%m-%d %H:%M")) ggplot(df, aes(x=dates, y=times)) + geom_point() +...
Making multiple plots with mapply
I think the problem came from the fact that the function is looking for a variable inside df named "var1". I don't know ggplots enough to circumvent this problem but, with base R plot, you can do: baseplot <- function(var1, var2){ plot(df[,var1], df[,var2], pch=19) } par(mfrow=c(1, 2)) mapply(baseplot, c("V1", "V3"),...
skip the empty dataframes and produce the output
r,merge,ggplot2,tidyr,rpostgresql
Judging from the error message, the data.frame that causes the error has neither rows nor columns, it seems to be NULL. So the easiest way would be to check for that situation and if the data.frame is NULL, create a a dummy that can be merge()d and gather()ed. What I...
R using ggplot2: “Error in value == ”primary“ : comparison is not allowed for expressions”
The cause of the error: At the beginning of the function call, the elements of value all have class "character". But when you hit value[value=="secondary"] <- label_secondary a bunch of those elements get replaced by expressions. So when you then try to do value[value=="primary"] <- label_primary R is trying to...
R: custom ggplot2 color-transform gives error in labels
There is a vectorized if, called ifelse. It also seems you are missing an extra minus. super_trans <- function() { trans_new('super', function(x) ifelse(x>0, x^0.5, -(-x)^0.5), function(x) ifelse(x>0, x^2, -(-x)^2)) } ...
Overriding panel.grid in ggplot2
If you look at theme_grey you can see that panel.grid.minor and panel.grid.major are both specified. When you specify panel.grid to a specific color, the minor and major grid lines would inherit this if a color wasn't specified for them. But there is. This works as expected: p_grid <- qplot(data =...
Scatterplot of Year-On-Year Correlation of Data in R using ggplot2
You want a data frame with a row for each team-year combination, containing the data for that year and the next year as well as the team name. You can actually get this without any split-apply-combine manipulation using base R functions: (to.plot <- data.frame(yearN=unlist(df[-ncol(df)]), yearNp1=unlist(df[-1]), team=rep(row.names(df), ncol(df)-1))) # yearN yearNp1...
Why is my graph's Y-axis not in the right order?
To sum up what was said in the comments : Your y-axis is indeed sorted but according to the character values (or rather the factor levels, as your variable was imported as factor) and not the numeric ones (so 1, 10, 11, ..., 2, 20, ...) There is 2 problems...
Adjust space between gridded, same-sized ggplot2 figures
You have set the 'widths' to be the maximums of the two plots. This means that the widths for the y-axis of the 'Petal Widths' plot will be the same as the widths of the y-axis of the 'Sepal Widths' plot. One way to adjust the spacing is, first, to...
Scaling Time in Hours in ggplot2
I wonder if it's a timezone thing. Look at the output of attributes(dfweek2$Time) and see if it has a tzone attribute. If it does, then when format is called without a tz parameter, it will convert the times from whatever time zone they're stored as to whatever system time zone...
ggplot equivalent for matplot
You can create a similar plot in ggplot, but you will need to do some reshaping of the data first. library(reshape2) #ggplot needs a dataframe data <- as.data.frame(data) #id variable for position in matrix data$id <- 1:nrow(data) #reshape to long format plot_data <- melt(data,id.var="id") #plot ggplot(plot_data, aes(x=id,y=value,group=variable,colour=variable)) + geom_point()+ geom_line(aes(lty=variable))...

ggplot + facet: dropping factors with no data
This can be done with na.omit in the following way: ggplot(na.omit(z), aes(EVTYPE, value, fill = variable)) + geom_bar(stat = "identity", position = "dodge") + facet_wrap( ~ variable, scales = "free") + theme(axis.text.x = element_text(angle=90, vjust=1)) Here's the result: Hope this helps....
Combine 2 plots (ggplot) into one plot and differenciate them
What if you change the linetype by group? p <- ggplot(dat = visual12, aes(x = as.numeric(weight), group = interaction(group, sexe), linetype=factor(group), col = sexe)) + stat_ecdf(geom = "step") + scale_colour_brewer(name = "sexe", palette = "Set1") + theme(axis.text = element_text(size = 15), legend.justification = c(1, 0), legend.position = c(1, 0), axis.text.x...
Creating new shape palettes in ggplot2 and other R graphics
You can create your own shape palette by specifying the Unicode values for the characters you want. You can find Unicode values for various geometric shapes here. For example: library(ggplot2) ggplot(mtcars[mtcars$carb %in% 1:4,], aes(wt, mpg, shape=factor(carb), colour=factor(carb))) + geom_point(size=5) + scale_shape_manual(values=c("\u25BA","\u25C4","\u25BC","\u25B2")) You can, of course, use Unicode characters in base...
How do I draw a better quality graph for this example using R ggplot() function? [closed]
While I agree this question is too broad, here is a quick redoing of the plot that looks quite a bit better than what you had and can hopefully give you a push towards deciding how you want to present your information. A few points and suggestions: Your labels are...
R: ggplot2: plot initiating at the axes
The answer first, then an explanation. Add the line: coord_cartesian(xlim=c(0,max(sfit$time))) to your ggplot object. A simple example: df <- data.frame(c(runif(10,0,1)),runif(10,0,1)) names(df) <- c("x","y") p <- ggplot(df, aes(x,y)) + geom_point() + scale_x_continuous(breaks=c(0,0.25,0.5,0.75,1.0), labels=c("0","0.25","0.5","0.75","1.0")) p gives you whereas, if you add to the above code p <- p + coord_cartesian(xlim=c(0,1)) p you...
How do I add a legend in ggplot2 using R?
Ditch your whole long ifelse monstrosity and just modify the ggplot call to be: ggplot(p04_NoNegative, aes(x=Distance.Traveled, y=GS_ReelRaiseLowerAngle)) + geom_line(aes(color=GS_Field),size=1.1) + ggtitle("p04 entire field") + ylim(0,0.6) + ylab("Reel Height (angle)")+ xlab("Distance (m)") + scale_x_continuous(breaks = x_axis_ef) + coord_cartesian(xlim = c(0,5000)) You can set the colors via scale_color_manual (assuming GS_Field is a...

R ggplot2 boxplot not properly shown when knitting html
The most likely difference is that you forgot to make quality into a factor within your rmd file. For example: set.seed(101) dd <- data.frame(quality = sample(6:9,size=200,replace=TRUE), residual.sugar = rnorm(200)) library(ggplot2) ggplot(aes(x = quality, y = residual.sugar),data=dd)+ geom_boxplot() dd2 <- transform(dd,quality=factor(quality)) ggplot(aes(x = quality, y = residual.sugar),data=dd2)+ geom_boxplot() ...
Draw geom_smooth only for fits that are significant
You can calculate the p-values by group and then subset in geom_smooth (per the commenters): # Determine p-values of regression p.vals = sapply(unique(d$z), function(i) { coef(summary(lm(y ~ x, data=d[z==i, ])))[2,4] }) plt <- ggplot(d) + aes(x=x, y=y, color=z) + geom_point() # Select only values of z for which regression p-value...
R shiny ggplot2 error 'Results must be all atomic, or all data frames'
It seems to be a problem with plyr, which is probably going to get fixed in the next R update. Until then you can fix it following these steps: Install platform specific development tools: Windows: Download and install Rtools33.exe from http://cran.r-project.org/bin/windows/Rtools/ Ubuntu or Debian based Linux: sudo apt-get install r-base-devel...

Set categorical axis labels with scales “free” ggplot2
The easiest method would be to create another column in your data set with the right conversion. This would also be easier to audit and manipulate. If you insist on changing manually: You cannot simply set the labels directly, as it recycles (I think) the label vector for each facet....
R language: how to use ggplot2 to plot multiple vectors on one graph with regression lines?
You want to gather VAR1 and VAR2 into the same column first, which can be done using the gather function in the tidyr package: library(tidyr) DF2 <- gather(DF, type, value, VAR1, VAR2) This will make DF2 tidy, with one row for each point you want on the plot (see this...

Try: ggplot(d, aes(x = Day, y = Length)) + geom_bar(aes(fill = Amount, order = -Location), stat = "identity") Notice how I swapped rev with -. Using rev does something very different: it stacks by the value for each row you happen to get if you reverse the order of values...
Strange performance of multi qplots to a figure in R when parameter of qplot includes list
This has to with with the lazy exaluation of parameters passed to qplot. The values aren't actually resolved till you print the plot. At that point, the value if i is just 6 after the looping. A better strategy would be plots <- lapply(1:6, function(i) { force(i) #required if you...
How to produce legend in ggplot by mapping aes_string from different data frames in ggplot?

R: melting a data.frame to use in ggplot2 for multiple y-value plot
There are two problems here. The first problem is that you use as.POSIXlt that produces lists instead of as.POSIXct which produces vectors. Therefore melt cannot do its job properly. Try this instead: df$time <- as.POSIXct(paste(df$Date, df$Time)) The second problem is that you group on the same variable that is used...
Assign same custom color to two lines coming from different data-frames but in the same plot
For the coloured lines, just add a colour argument p = ggplot() + stat_summary( data = d0_400, ..., geom="line", colour = "#hexnum" ) Also, a quick google of the optional question took me to here: The solution provided is p = p + guides(shape=guide_legend(override.aes=list(size=5))) ...
Dodge points in point char with ggplot2

Issue with geom_text when using position_dodge
Just one minor change solves the issue. You need to specify group=x inside your geom_text(aes(...)) call. ggplot(df) + geom_bar(aes(z, y, fill=x), position=position_dodge(width=1), stat="identity") + geom_text(aes(z,y,label=perc, group=x), position=position_dodge(width=1), size=4) ...
ggbiplot: how to maintain group colors after changing point size?
This is a general ggplot2 syntax issue, I think, as it occurs with simpler examples (e.g., ggplot(mtcars) + geom_point(aes(disp, hp, color=cyl), size =mtcars$model)) But, I think this will work for you: geom_point(aes(X1, X2, color=habitat, size = point.size)) + scale_size_identity() ...
ggplot2 & facet_wrap - eliminate vertical distance between facets

How to plot a lagged time series?
You can use tail to get a lagged version a vector: tail(x,-1) But within ggplot2 aesthetics must either be length one or having the same length, so you should append a value to the lagged one in order to plot it against the original vector. For example: x= 1:10 qplot(x=x,y=c(tail(x,-1),0))...

Log Scale Transformation in R for ggplot2
The book of Hadley is already quite old in regards to dynamics in programming. To my experience ggplot2 is quite a dynamic package and these details often change (also see questions referring to how to turn the labels on the axis). Due to that I prefer to check stuff like...

How to stack error bars in a stacked histogram using geom_errorbar , ggplot?
What is happening here is that ggplot is not stacking the error bars (they would have to be summed) so you will have to do that by hand (and it seems that Hadley thinks that this is not a good idea and wil not add this functionality). So doing by...
Create abbreviated legends manually for long X labels in ggplot2
Rotation solution suggested by Pascal Rotate the labels and align them to the edge : datas %>% ggplot(aes(x = label, y = freq)) + geom_bar(aes(fill = type), stat = "identity") + theme(axis.text.x = element_text(angle = 90, hjust = 1)) ...
How to execute .r files to output figures?
First, you need to ensure that the R software where you will run your scripts, has all required packages installed. Second, make sure the data is somehow available. This should usually make all scripts runnable. If you want to save ggplot-figures, use the ggsave-function after each plot is generated. This...
Dynamically create expression for ggplot legend?
ggplot(plot.df, aes(x, y, colour = grp)) + stat_smooth(method = "loess", se = F) + geom_line(aes(y = pred)) + scale_color_manual(values = setNames(geom.colors, paste0("x^",poly.degree)), labels = setNames(lapply(poly.degree, function(i) bquote(x^.(i))), paste0("x^",poly.degree))) It's important to ensure correct mapping if you change values or labels in the scale. Thus, you should always use named vectors....
R, ggplot2, facetted histogram, decending order, factor x-axis labels
you can use reorder and interaction between groups and Category like this ggplot(df,aes(x=reorder(interaction(Category, Group), -Amount, sum),y=Amount)) + geom_bar(stat='identity') + facet_wrap(~Group,scales='free_x') + labs(title="Some Random Histogram with Facets") ...
Plotting in R 3.1.2 [closed]
Perhaps something like this is what you're after, but this would be easier if you would provide sample data and be more descriptive in the exact question you are asking: library(ggplot2) library(dplyr) library(tidyr) df <- data.frame(id = 1:400, state = state.abb, ind1 = rnorm(400), ind2 = rnorm(400), ind3 = rnorm(400))...
Conditionally change ggplot facet background with date axis
The cause of your error message was that you tried to map an aesthetic to a column that doesn't exist in your data, in this line: geom_rect(data = facetcond, aes(fill = "red"), You are not mapping an aesthetic, but telling ggplot to fill the rectangle with red. The line should...
Overlaying jittered points on boxplot conditioned by a factor using ggplot2
r,ggplot2,overlay,boxplot,jitter
Welcome to SO! Here's my attempt. It's a bit clumsy, but does the job. The trick is to map x to a dummy variable with manually constructed offset. I'm adding a fill scale to highlight point positioning. mtcars$cylpt <- as.numeric(factor(mtcars$cyl)) + ifelse(mtcars$am == 0, -0.2, 0.2) ggplot(mtcars, aes(factor(cyl), mpg)) +...
making a choropleth from SpatialPolygonsDataFrame- ggplot vs ggplot2 vs plot?
Shamefully taken from Ari's post on gis.stackexchange.com. See the link for pictures. There are more examples here. library(sp) Srs1 = Polygons(list(Polygon(cbind(c(2,4,4,1,2),c(2,3,5,4,2)))), "s1") Srs2 = Polygons(list(Polygon(cbind(c(5,4,2,5),c(2,3,2,2)))), "s2") SpDF <- SpatialPolygonsDataFrame( SpatialPolygons(list(Srs1,Srs2)), data.frame(z=1:2, row.names=c("s1","s2") ) ) spplot(SpDF, zcol="z") ...
replacing NAs by value but excluding from geom_smooth
One way to do it is to store your data into two different data frames : df2 <- df df2[is.na(df2)] <- -5 And plot them into two different layers : ggplot() + geom_point(data=df2, aes(x,y)) + geom_smooth(data=df, aes(x,y), method="lm", fullrange=TRUE) But maybe a cleaner way to do it would be to...
geom_rect() main variable not found
OK. This: geom_rect(inherit.aes = FALSE, data = rects, aes(xmin = xstart, xmax = xend, ymin = -Inf, ymax = Inf, fill = col), alpha = 0.4) ...
Extracting data from TraMineR for use in other plotting packages (e.g. ggplot2)
All the information (sequences, alphabet, color palette, short and long state labels, position labels, ...) used by seqIplot is in the state sequence object you define with seqdef from your raw data. So just explore your object using attributes library(TraMineR) data(mvad) ## create a state sequence object from columns 17...
Grouped barplot in ggplot2 in R
If you want separate bars for each gear, then you should add fill=gear to the aes in geom_bar: ggplot(cdata[cdata$year==2012 & cdata$sitecode==678490,], aes(x = factor(month), y = totalvalue, fill=gear)) + geom_bar(stat = "identity", position="dodge") + labs(x = "Month", y = "Total value") this gives: When you want to make a plot...
Align text right justified but center of each box in geom_text
Use hjust=0.5 in geom_text() and pad the labels for positive numbers appropriately, i.e. prepend space characters to obtain labels of equal length: df_graph$text <- format(round(df_graph$value, 2)) ...
Equal distance among all points on an axis
You might want to convert your x-values into factors. Right now, R assumes that your x-values are numbers and hence puts the appropriate space between them (the difference between 5,884 and 13,957 is larger than the difference between 21,013 and 28,708). However, you probably think of the numbers as names...
How do I put multiple boxplots in the same graph in R?
r,plot,ggplot2,rstudio,boxplot
ggplot2 requires that your data to be plotted on the y-axis are all in one column. Here is an example: set.seed(1) df <- data.frame( value = runif(810,0,6), group = 1:9 ) df library(ggplot2) ggplot(df, aes(factor(group), value)) + geom_boxplot() + coord_cartesian(ylim = c(0,6) The ylim(0,6) sets the y-axis to be between...
How to customize lines in ggpairs [GGally]
I hope there is an easier way to do this, but this is a sort of brute force approach. It does give you flexibility to easily customize the plots further however. The main point is using putPlot to put a ggplot2 plot into the figure. library(ggplot2) ## First create combinations...
Limit the color variation in R using scale_color_grey
I think this code should produce the plot you want. However, without your exact dataset, I had to generate simulated data. ## Generate dummy data and load library library(ggplot2) df4 = data.frame(Remain = rep(0:1, times = 4), Day = rep(1:4, each = 2), Genotype = rep(c("wtb", "whd"), each = 4),...
Why can I not get the x axis labels to show in my graph?
Try removing the breaks argument to scale_x_discrete: f + ggtitle("Alcohol Usage by Personality Trait")+ labs(x="Personality Trait", y="Alcohol Usage")+ scale_x_discrete( # breaks=c("open","extra","con","agree"), labels=c("Openness","Extraversion","Conscientiousness","Agreeableness") ) + theme( plot.title=element_text(size=15,face="bold",vjust=.5), axis.title.x=element_text(size=12,face="bold",vjust=-.25), axis.title.y=element_text(size=12,face="bold",vjust=1), axis.text.x=element_text(size=10,face="bold",color="black"),...
How to add inbetween space in nested boxplots ggplot2
I have fixed a similar problem in an ugly (but effective for me) way by creating a dataframe with the same plotting variables as my original data, but with x (or y) positioned or factored that it fits between the two points I want to separate and missing values for...
error with lapply on anonymous ggplot function
You are missing a paranthesis to close ggtitle() as names() also requires a closing paren. if (inputMethodP == "WITHINFILE") { par(mfrow = c(5, listPortions)) plotList <- lapply(RangeStatResultP, function(listPart) { ggplot(matrixPart, aes(x = factor(Var2), y = value)) + geom_violin()+ ggtitle(names(listPart)) + xlab(listnum) + ylab("Coverage") + stat_summary(fun.y = median, geom = "point",...
Ploting the world map in R
You can also work in "layers" as other GIS environments let you (which will also let you not merge the data). This can be achieved in many ways, but I like to use geom_map: library(ggplot2) library(dplyr) WorldData <- map_data('world') WorldData %>% filter(region != "Antarctica") -> WorldData WorldData <- fortify(WorldData) df...
geom_vlines multiple vlines per plot
r,ggplot2,time-series,timeserieschart
This is the solution: library(ggplot2) library(reshape2) library(ecp) synthetic_control.data <- read.table("/Users/geoHeil/Dropbox/6.Semester/BachelorThesis/rResearch/data/synthetic_control.data.txt", quote="\"", comment.char="") n <- 2 s <- sample(1:100, n) idx <- c(s, 100+s, 200+s, 300+s, 400+s, 500+s) sample2 <- synthetic_control.data[idx,] df = as.data.frame(t(as.matrix(sample2))) #calculate the change points changeP <- e.divisive(as.matrix(df[1]), k=8, R = 400, alpha = 2, min.size = 3)...
ggplot2: can't sort x axis by y value
You need to give reorder the sum function, otherwise it defaults to using the mean function. Then, I put a - in front of amount to get the order reversed. p=ggplot(data=hp) p+geom_bar(binwidth=0.5,stat="identity")+ # aes(x=reorder(class,-amount,sum),y=amount,label=amount,fill=year)+ theme() ...
Only show last four labels on bar graph
Thanks to @user20650 for the quick response. Subsetting the gem_text did the trick. Thank you very much! Here is the updated code: library(data.table) library(ggplot2) df <- data.table(x= c(1, 2, 3, 4, 5,6,7,8,9,10), y=c(4, 1,-3,-5,4,1,2,4,2,-3)) ggplot(df, aes(x=x, y=y)) + geom_bar(stat="identity") + geom_text(data=subset(df, x>6), aes(y=y, ymax=y, label=y), position= position_dodge(width=0.9), vjust=-.5, color="red") ...
Plotting with ggplot through calling another function
Your example is not very clear because you give a call but you don't show the values of your variables so it's really hard to figure out what you're trying to do (for instance, is method the name of a column in the data frame pl1, or is it a...
