Stopwatch function in R

Question

Is there an R timer or stopwatch function similar to MATLAB\'s tic/toc?

Answer 1

As of the date 2015-03-25, and possibly earlier, the pracma package contains the functions tic() and toc().

Example:

> library(pracma)
> tic()
> for(i in 1:10000) mad(runif(10000))    # kill time
> toc()
elapsed time is 18.610000 seconds
