Many thanks in advance! > Adam, First, is possible 32bit XP use all your 4Gb? Second, I think you say "gc" whem say "gs", so in my computer (Ubuntu 64bit with 4Gb): > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 188975 10.1 407500 21.8 35 18.7 Vcells 169133 1.3 786432 6.0 786378 6.0 > gc(reset=T) used (Mb) gc trigger (Mb) max used (Mb) Ncells 188951 10.1 407500 21.8 188951 10.1 Vcells 168893 1.3 786432 6.0 168893 1.3 If you read gc help: reset: logical; if 'TRUE' the values for maximum space used are reset to the current values. Other issue is options for rgui command. Have a option "--max-mem-size" that you modify to expand you RAM avaiable -- Bernardo Rangel Tura, M.D,MPH,Ph.D National Institute of Cardiology Brazil __ 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.

Yes, I did. But this only matters if R requests a memory block of size bigger than 2GB at one time. As I wrote, I had 1.5GB available of physical memory out of my 4GB. > gc(), I think. Yes, indeed.
