Progress Bars in R

Recently, I’ve had a lot of time consuming tasks running in R where it’s nice to know how the computer is doing. I usually just output the name of the current iteration or a dot or something but I finally decided I should figure out how to make a nice progress bar in R. It turns out it’s really simple since it’s already builtin with the txtProgressBar function. So you can do something like:

[R] numberSteps<-10 pb <- txtProgressBar(min = 0, max = numberSteps, style = 3) for(i in 1:numberSteps){ setTxtProgressBar(pb, i) Sys.sleep(1) } close(pb) [/R] A text progress bar in R

That’s good enough for me but there’s also winProgressBar for a fancy Windows progress bar and tkProgressBar (in the tcltk package) if you really want to get fancy.
