Stopwatch function in R

Question

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

Answer 1

Direct equivalents of tic and toc do not exist.

Please see help(system.time) as well as the R Extensions manual about profiling. Discussions of profiling and profiling tools is also in the 'Intro to HPC with R' slides referenced on the High Performance Computing with R taskview
