In my previous post, I wrote about displaying a Windows progress bar (useful when going through long for-loops). In the comments, a couple of users recommended that I check out pbapply(). This function is great too (and works on all platforms)! Basically, it allows you to perform all the apply() functions – apply(), lapply(), sapply(), etc. and adds in a progress bar. Here is some code showing a very simple example:
###### Packages library(pbapply) ###### Data n<-1000 mat<-matrix(rnorm(n),ncol=10,nrow=100) ###### apply() vs pbapply() x<-pbapply(mat,1,sum) y<-apply(mat,1,sum) x-y
