Hey,
I just read another post about calling R from C. Someone on
stackoverflow (DWin makes me suspect its David W.?) referenced this:
http://www.math.univ-montp2.fr/~pudlo/R_files/call_R.pdf
Which made me think: Why is a loop in R bad, but in C not?
And where exactly does looping cost the most? I wrote a piece of code
for my bachelor's thesis where I loop from 1 to 500, and estimate a
boosted model in every iteration. The procedure takes 2-6 minutes. In
this example the loop (instead of some kind of apply()) shouldn't cost
too much time, right?
I suspect it's way worse if someone would loop from 1 to 10000 and
perform only a small task (a mean(), for example) in each loop. Can
someone confirm this?
Regards,
Alex
