This appears to be the sort of query that (with apologies to other R gurus) only Brian Ripley or Luke Tierney could figure out. R generally passes by value into function calls (but not *always*), so often multiple copies of objects are made during the course of calls. I would speculate that this is what might be going on below -- maybe even that's what you meant.
Just a guess on my part, of course, so treat accordingly. -- Bert On Mon, Feb 27, 2012 at 1:03 PM, Sam Steingold <s...@gnu.org> wrote: > It appears that the intermediate data in functions is never GCed even > after the return from the function call. > R's RSS is 4 Gb (after a gc()) and > > sum(unlist(lapply(lapply(ls(),get),object.size))) > [1] 1009496520 > > (less than 1 GB) > > how do I figure out where the 3GB of uncollected garbage is hiding? > > -- > Sam Steingold (http://sds.podval.org/) on Ubuntu 11.10 (oneiric) X > 11.0.11004000 > http://www.childpsy.net/ http://camera.org http://truepeace.org > http://www.PetitionOnline.com/tap12009/ http://thereligionofpeace.com > Modern man is the missing link between apes and human beings. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. -- Bert Gunter Genentech Nonclinical Biostatistics Internal Contact Info: Phone: 467-7374 Website: http://pharmadevelopment.roche.com/index/pdb/pdb-functional-groups/pdb-biostatistics/pdb-ncb-home.htm ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
