Java scanner adding variable conditions
java,java.util.scanner,conditional-statements
I suggest you to use the regular expression in the hasNext() function as follows to have a finer control, for example use the following pattern if you look for the numbers, sc.hasNext("[0-9]+") Here is the documentation for the hasNext(String pattern) function, public boolean hasNext(Pattern pattern) Returns true if the next...
Conditional with statement in Python
python,conditional,indentation,conditional-statements,with-statement
If you want to avoid duplicating code, you could do something like: class dummy_context_mgr(): def __enter__(self): return None def __exit__(self): return False with get_stuff() if needs_with() else dummy_context_mgr() as gs: # do stuff involving gs or not or make get_stuff() return different things based on needs_with()....
R filtering logic
r,filter,logic,conditional-statements
It's kind of confusing to understand what you want, but it seems like if a test session has a test.url "not_in_list", then all test.code_maps for that test session should be 0. If so, this should work test.df$test.code_map<-ifelse( ((test.df$test.start_flag == 1 & test.df$test.url=="in_list")| (test.df$test.start_flag == 0 & test.df$test.url=="in_field"& test.df$test.session!="B") & !test.session...
Bitwise operator in if statement

It loops over all values from 0 to n, and for each of these: It loops over each bit in the value. if the value is set: It executes //code Lets examine the complex part: if(i & (1<<j)) 1<<j is a common way to set the jth bit (starting from...
Finding numeric element patterns using conditionals R

You could try the following: library(dplyr) # for lead() #1 y1 <- as.integer(x > 7 & lead(x) %in% 1:2) #[1] 0 1 0 1 0 1 0 0 0 0 0 0 0 0 #2 y2 <- as.integer(x >= 7 & (lead(x) <= 4 | lag(x) <= 4) & !y1)...
C++, Adding conditions in class vars
c++,class,object,conditional-statements
I assume you know why conditions field and condition parameter are both simple boolean variables. If that is true, it could be very simple, but you should replace addCondition with andCondition and orCondition : void obj::andCondition( bool cond ) { conditions = conditions && condition; } void obj::orCondition( bool cond...
R: Nearest Neighbour Imputation for Non-NA possible?

Here's one way, using na.locf(...) in package zoo. # replace -1,1,3 with NA DF1 <- as.data.frame(sapply(DF1,function(x){x[x %in% c(-1,1,3)]<-NA;x})) library(zoo) # carry last obs forward into NAs, retaining NA at the beginnig of each row result <- apply(DF1,1,na.locf,na.rm=FALSE) result <- as.data.frame(t(apply(DF1,1,na.locf,fromLast=TRUE))) result # v1 v2 v3 v4 v5 v6 v7 #...
Conditional statement not working as expected
linux,shell,conditional-statements,konsole
You want to test with if [ $(expr $cr % 3) = 0 ]; then ... because this [ $ct%3==0 ] tests whether the string $ct%3==0, after parameter substitution, is not empty. A good way for understanding this is reading the manual for test and look at the semantics when...
SAS statistic parameters of specific variables from data with conditions
variables,statistics,sas,conditional-statements,proc
I wouldn't create a separate data step as suggested by Alex A. That can be a bad habit to develop as, with large datasets, it can be extremely costly in terms of CPU. Rather, I would subset the Proc Means call but slightly differently from Alex A's suggestion since you...

You can use logical arrays to replace the conditional statements and scale them with appropriate scaling factors for the final output - %// Logical arrays corresponding to the IF and ELSEIF conditional statements case1 = res1>D & res2<-D case2 = res1<-D & res2>D %// Get the final output after multiplying...

Trouble with a loop statement in R
r,if-statement,for-loop,conditional-statements
Not much clear, but I'd assume you want to know at which point the cumulative sum of w*z reaches the five per cent of sum(w*z), while following the order of z. If that's correct, you can try this: #for every z get the order indices indices<-order(z) #sort both z and...
Conditional statement in daa.R of the R “matchingMarkets” library
r,conditional-statements,parentheses
When you ask R if 0 %in% x where x is a logical vector, R will first convert x to a numeric vector where FALSE becomes 0 and TRUE becomes 1. So essentially, asking if 0 %in% x is like asking if x contains any FALSE. This is arguably pretty...
Using echo within conditional statement
php,html,conditional-statements
If this is WordPress and its _e() function, you may want to break up your echo lines into something like the following example: <?php $mylocale = get_bloginfo('language'); if($mylocale == 'en' || $mylocale == 'en-US') { echo '<div class="timer-col"> <span id="days"></span> <span class="timer-type">'; _e('days ', 'framework'); echo '</span> </div>'; } else...

More efficient way of doing multiple if else statements
java,if-statement,conditional-statements
If your bounds are completely arbitrary (unlike the example you have posted), then your idiom is almost as fast as you can get. You should just eliminate the redundant lower bound checks. First ensure that the result is positive and after that just test the upper bounds. If you use...
