Just wanted to start a discussion on whether R could ship with more appropriate GC parameters. Right now, loading the recommended package Matrix leads to: > library(Matrix) > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 1076796 57.6 1368491 73.1 1198505 64.1 Vcells 1671329 12.8 2685683 20.5 1932418 14.8 Results may vary, but here R needed 64MB of N cells and 15MB

Dear R people, I wonder if some kind person can tell me the correct syntax to set the R_VSIZE environmental variable. I tried R_VSIZE = 10M in ~/.Renviron and also export R_VSIZE = 10M. These don't seem to work. I scrounged around looking for details about this, couldn't find any, got fed up. Faheem. -.-.-.-.-.-.-.-.-.-....

...ection is almost 2/3 of that. My actual use case is a package that creates an ensemble from a variety of cross-validated regressions, and exhibits the same poor performance. Is this expected behavior? I've found that I can reduce the garbage collection time to a tolerable level by setting the R_VSIZE environment value to a large enough value: nate at haswell:~$ time R_VSIZE=1GB Rscript gc.R Loading required package: Matrix Loading required package: methods [1] 0 0 0 0 0 [1] 0.716 0.025 0.739 0.000 0.000 real 0m7.694s user 0m7.388s sys 0m0.309s I can do slightly better with even higher values,...

...{unless --no-environ is specified} ~/.Renviron (if there) is read as an 'sh' script before R is called, then R looks ((for the site-wide Rprofile and then)) for .Rprofile in the current directory and then for ~/.Rprofile (in the user's home directory). I'd like to set R_NSIZE and R_VSIZE ``project dependent'' automatically, and therefore would like .Renviron also searched in the currenct directory before the $HOME directory. (setting --nsize or --vsize explicitly would always override as they should). Is this desired? Is is portable (at least) to Windows? In the window...

When I use the -v I can modify the size of the heap, as assessed by gc(), but the -n key seems to be without effect ? On a machine with 48 mB ram I can load the libraries without problem, but on my own 36 mB ram machine, I get dynload problems with the larger, eg survival4. Any suggestions ?

Full_Name: Markus Neteler Version: 1.0.0 OS: Linux 2.2.10/i686 Submission from: (NULL) (130.75.72.37) Hi, I wanted to "check" the R.GRASS GIS interface from Roger Bivand: http://www.geog.uni-hannover.de/grass/statsgrasslist.html using R CMD check --vsize=10M GRASS but: [error message shortened] > G <- gmeta() Error: heap memory (6144 Kb) exhausted [needed 1024 Kb more]

For some of my packages I am getting a segmentation fault in Linux when I use R CMD check. (Using R 1.0.1) The segmentation fault does not happen in Solaris and in some cases it does not happen in Linux if I set R_NSIZE and R_VSIZE much higher than I need in Solaris. Should I expect a segmentation fault if there is not enough memory for R CMD check, or are these unrelated?
