Hi, I have some code with a bunch of apply/sapply/lapply calls to different functions. I am trying to profile it using Rprof, however the resulting summary looks like this (output from 'R CMD Rprof'): % total % self total seconds self seconds name 100.00 14.52 0.32 0.05 "source" 99.99 14.52 0.24 0.04 "eval.with.vis" 88.21 12.81 12.21 1.77 "FUN" 86.04 12.49 4.08 0.59 "lapply" 82.90 12.03 0.05 0.01 "sapply" 25.80 3.75 2.72 0.39 "apply" All of the functions called by the apply/sapply/lapply calls seem to be getting munged into a single "FUN" reference. Is there a way to get Rprof() and/or summaryRprof() to independently report the different functions being 'apply'-ed? Thanks. -David
