Dear R-ers, somehow it is not possible to increase nsize to more than 20000k. When I specify e.g. > R --vsize=10M --nsize=21000K the result is: free total (Mb) Ncells 99658 350000 6.7 Vcells 1219173 1310720 10.0 Maybe I have overlooked s.th....

.... Distributions can be of various types, with various parameters, but we ran into some problems. I started testing on a simple list of rnorm-based objects. I was a little surprised at the RAM storage requirements, here's an example: N <- 10000 closureList <- vector("list", N) nsize = sample(x = 1:100, size = N, replace = TRUE) for (i in seq_along(nsize)){ closureList[[i]] <- list(func = rnorm, n = nsize[i]) } format(object.size(closureList), units = "Mb") Output says 22.4 MB I noticed that if I do not name the objects in the list, then the storage drops to...

Dear all, I don't get it: First of all, the help doesn't say what are the memory limits of R. Say, what's the max heap size for instance ????

Using such an R process will lead to a segmentation fault...

An "xdr real data read error occured" and R tells me to delete .RData or increase memory. I WON'T delete this file and changing the max-nsize to 40600k did not change a thing. I am running R from Windows with the command line : "$path\Rgui.exe" --min-vsize=10M --vsize=60M --max-vsize=200M --min- nsize=1000k --nsize=2900k --max-nsize=40600k Please let me know the answer as I cannot go on with my work!

...}) ...and a win2000(XP2000+,1GB) machine makes it in several minutes, but my linux notebook (XP2.6GHZ,512MB) don't get success after some hours. I recognize that the cpu load is most time relative small, but the hardisk have a lot of work. Is this a problem of --max-vsize and --max-nsize and i should play with that, because i can't believe that the difference of RAM is the reason? Have anybody experience what is an "optimal" setting with i.e. 512 MB RAM in Linux? Many thanks for help and comments regards,christian

G'day R friends, I didn't get any replies on the main list so I thought I'd try with the experts. I was wondering if anyone's ported R to os390. If so, are the vsize and nsize limits the same as other platforms?

In Maindonald?s UsingR text, on pg 3, there?s a footnote that reads: "If you want larger memory space than the default you may want a target akin to <path to binary>\rw091\bin\rgui.exe --visize 30M --nsize 1000K [The default is --vsize 6M --nsize 250K (...)] I tried that, but R still crashes.

Dear R-users, I am trying to run some simulations in batch mode. In an older version of the program, I used rterm --vsize=100M --nsize=5000K --restore --save <input file> output file, however, in the new version R 2.2.0 , the parameters vsize and nsize are ignored. I can use the command memory.limit to increase memory, but I am not sure if this corresponds to vsize and nsize. Does anyone know how can I set these quanti...
