[R] How to increases the Memory size for R in Batch mode
hello everybody!! I am using "Rcmd BATCH" command to run simulation on R in batch mode on win98 machine. Would it be possible to increase the memory size of R; if so how and what is the default memory size used, and what is the limit to which I can increase the memory size. My machine configurations: 512MB Ram with Intel P-III processor working at 1GHz speed. Win98 and R 1.4.1 Thanking you all in advance for your help, -Jag Jagadish Rangrej ( Statistician ) Chalmers Research Group (CRG) CHEO Research Institute, Ottawa, ON 613-7383951 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

On a 32-bit OS that has an appropriate memory managment, up to 2GB, in principle. I think there are reasons of a 512MB limit (at least in efficiency) on the (more or less) DOS based Windows versions (e.g. Win98). There something about that in the mailing list archives, if you are interested....> > My machine configurations: > 512MB Ram with Intel P-III processor working at 1GHz speed. > Win98 and R 1.4.1 > > Thanking you all in advance for your help,This is a FAQ and mentioned in the R for Windows FAQs and in the help for ?Memory and the mailing list archives. The solution is to use the option --max-mem-size ... Something like Rcmd BATCH --max-mem-size=450M yourRfile.R should do the trick.
