Rprofiling

If f is your function just do this:

Rprof(); f(); Rprof(NULL); summaryProf()

Also check out the profr package and for benchmarking check out
?system.time and http://rbenchmark.googlecode.com

Dear R People:

Could someone recommend a good reference for Rprofing, please?

Thanks,
Erin

Well, you have the notes of the 'high performance computing with R' tutorial
at last summer's useR conference giving you examples using both 'base R'
functions and add-on packages.  That could be a starting point.

Beyond that, I may have an example of profiling external libraries for the
next 'high performance computing with R' tutorial preceding the R / Finance
conference (http://www.RinFinance.com) next month --- and I happen to know
you'll be attending that. So see you there, and if you have more concrete
questions, let us know.

Hth, Dirk
