Keep getting errors when trying to knit a PDF using R Markdown
For those of you who are having similar issues. I fully uninstalled MIKTEX and reinstalled a complete version of proTeXt (which is basically a full install of MIKTEX plus a LaTeX IDE called TeXstudio) and it fully fixed my issue. I am now able to compile PDFs through RMarkdown without...
Save View() output of RStudio as html

How to interact with websocket from within R
I had a similar question a while back and it was confirmed to me by Joe Cheng (maintainer of httpuv) that httpuv is a websocket server only. That still seems to be true with httpuv 1.3.2 dated 2014-10-22.
Convert a date to a day number (monday = 1, tuesday = 2) in R

You should use print or cat to force output : ```{r} for(i in seq_along(dflist)){ print(paste('head data set:' , names(dflist)[i])) ## sub title print(head(dflist[[i]])) ## content cat(rep("*",20),'\n') ## separator } ``` ...
Multiple plots in one figure in R: Error if only ONE column
RStudio will throw that error if the plot window is sized too small for what you are trying to plot. You could try dragging that plot window larger relative to the console etc, or you could write your plot directly to a file, for instance using pdf() and dev.off().
In “R” iterate over specific columns
r,loops,for-loop,rstudio,lapply
This seems simple enough. I didn't test as we weren't given data but you should get the gist. myFun<-function(col) { myDF$multiple[grep(" Mbps",myDF[,col])] <- 1000000 myDF[,col] <- gsub(" Mbps","",myDF[,col]) myDF$multiple[grep(" Kbps",myDF[,col])] <- 1000 myDF[,col] <- gsub(" Kbps","",myDF[,col]) myDF$multiple[grep(" bps",myDF[,col])] <- 1 myDF[,col] <- gsub(" bps","",myDF[,col]) myDF[,col] <- as.numeric(myDF[,col]) * myDF$multiple }...

What's the difference in using a semicolon or explicit new line in R code
At the console, the script is evaluated as soon as the a line ends with a complete statement. Hence, this: temp_a temp_b <- 1 temp_c <- 2 is equivelent to calling this: source(textConnection('temp_a')) source(textConnection('temp_b <- 1')) source(textConnection('temp_c <- 2')) in which each line is evaluated as soon as it is...
Plot a histogram of means and label individual mean/PDF
Here are two ways of adding a label. First, some random data and the regular histogram: set.seed(0) means <- rnorm(1000, 4.5, 0.2) hist(means) One way to add what you want is plot one point where you want, using points() points(x=means[1], y=0, pch="X", cex=1.5) Use y for the vertical position, pch...
How to configure R-3.1.2 with --enable-R-shlib

Using R Studio Console commands not parsed in Knitr markdown file
You have to define the object in the Knitr code. Knitr, by design, operates in a clean room and has to be self-contained. It doesn’t look at your existing RStudio environment (in fact, that would be terrible because it would make the resulting code entirely unreproducible). As an example, here’s...
Arranging subgroups in ggplot [duplicate]
Just add this before ggplot(): data$group <- factor(data$group, levels = c("Nor", "i_GS", "GS")) Idea is that ggplot reads from factors the way they are arranged in data frame. Hence you have to rearrange the factor in the data frame if you want to see them visualized differently....

RStudio and RGUI may be using different defaults for setInternet2(), so try running setInternet2(use=FALSE) at the beginning of your session. Here is an explanation from RStudio (2013): Also we call setInternet2(use=TRUE) on startup which takes proxy settings from Internet Explorer to make proxies work in the majority of cases. We...
Generating LaTeX tables instead of text in Rstudio
R markdown in R Studio makes this sort of thing much nicer. Blocks of R code can be declared with three backticks{r}code and then inline code with a single backtick and r. The following does something similar to what you want. --- title: "Untitled" author: "user" date: "Tuesday, May 05,...

Missing projection file in R's rgdal package for geospatial analysis
I had a quick Google and came across this post which suggests this was an OS X error where the packages were built incorrectly.

How to read every .csv file in R and export them into single large file
You can use lapply to read all the files, clean and format them, and store the resulting data frames in a list. Then use do.call to combine all of the data frames into single large data frame. # Get vector of files names to read files.to.load = list.files(pattern="csv$") # Read...
.Rd file generation in a package using Rcpp

Render R Presentation from the command line
r,markdown,rstudio,knitr,slidify
I asked this question in on RStudio Support Community page, and the 'official' answer was no. A colleague looked at the code on github and verified the method is only called from the drop down UI. Looks like to do this you would have to actually compile your own wrapper.

Creating a loop with character variables on R - for two-sample t.test
I am assuming you are doing the regression of each indicator against the same f.

Running R and RStudio on Dropbox [duplicate]
Sounds like there are two separate aspects to your question: Can you share the R & RStudio application/executables Can you share the R scripts/project documents Regarding 1, to share the application/executables, you could follow the portable Rstudio approach from @hrbrmstr. That's going to require you providing the correct versions for...

Differences in R Markdown syntax highlighting for in-line code

Is there any direct method to fetch data from a Couchbase server to R Studio?
Couchdb has restful http interface so you can query the database directly using that. There is this package for R that should make it easier for you: http://cran.r-project.org/web/packages/RCurl/index.html Here is an example of a Uri that might be used to query a couch view: /database/_design/designdocname/_view/viewname.

RMarkdown: Why do I have to reinstall all packages everytime I knit?
Since "require returns (invisibly) a logical indicating whether the required package is available" you can conveniently use it for programming to either load the package or, if it's not available, (try to) install it and load it afterwards. So you could modify your code along the lines of: if (!require(dplyr))...
unable to get column names when using skip along with read.csv

If you want a function that takes vectors A, B, C, and D and input and outputs a sorted version of them, you can try: sortAll <- function(A, B, C, D) sort(c(A, B, C, D)) And then you can run it with something like: A <- c(1,2,2,3) B <- c(5,6,7,8)...
finding rows which don't have NA in a particular column if it already didn't have any NA
The problem is not limited to NAs. It happens if the indexing vector is empty. The hope is that the whole vector will be returned, but actually, x[numeric(0)] (x indexed by a vector of length 0) returns an empty vector. For example, consider the following: > df[ c(-1), ] #...
Error while using rarecurve() in R
There is no reproducible example. However, your usage is wrong. Function rarecurve needs input data of counts: it samples individuals from each sampling unit (row), and therefore you must have data on individuals. The error is caused by the use of wisconsin(lac.com.data): after that all rowSums(lac.com.data) will be 1, and...
Title not showing on R Markdown with knitr when rendering markdown file
Markdown does not have such a concept as "title". HTML has the <title> tag (and Pandoc also puts the title in <h1> for the HTML output from Markdown so you can see it from the HTML body), and LaTeX has the \title{} command. It is not unexpected to me that...

How do I put multiple boxplots in the same graph in R?
r,plot,ggplot2,rstudio,boxplot

suppress console output in r markdown, but keep plot

Is there a way to have a barplot and a stacked barplot on the same graph using barplot or ggplot?
Using ggplot, I would do something like one of these. They plot the two sets of data separately.

The second generates the two plot objects separately, then combines the two plots and the legend...

using -knitr- to weave Rnw files in RStudio
After spending hours to try to figure out the problem, I updated R (v 3.2.0) and everything works fine now. It is not clear if the problem was due to some packages conflict, for sure it wasn't an RStudio problem (as I had initially thought).
Source R script using 32 bit R from 64 bit RStudio
I think you want to use Rscript.exe to run the file, rather than R.exe. You can do this by just using /bin/i386/Rscript.exe your_rfile.R - this is how I would execute R code from the command line in Windows.

Is there an Rstudio keyboard shortcut to open up the file that contains the source code to a function you've written?
If you are within a package then F2 will navigate to the source file of functions defined within that package (it would be nice if you could also go to other packages but that doesn't work yet). You can also use Ctrl+. to do a typeahead search of all functions...

Shiny selectInput produces a list of numbers
Since your example isn't reproducible, I'm going to guess that class(CompanyNames$Companynm) is a "factor" rather than a "character". When you use c() on a factor, it strips all the information used for the levels and converts it to a simple numeric column. For example x<-data.frame(a=c("apple","banana","pear")) x$a # [1] apple banana...
how to extract specific paragraphs from a text file in R [closed]
