Stopwatch function in R

Question

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

Answer 1

A very simple equivalence with tic and toc that you could have:

tic=proc.time()[3]

...code...

toc=proc.time()[3] - tic

Where the [3] is because we are interested in the third element in the vector returned by proc.time(), which is elapsed time.
