I've been doing a number of similar measurements, and have come to the same conclusion. R is currently very conservative about memory usage, and this leads to unnecessarily poor performance on

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

Hi all, I'm having a very minor problem. Most every time I use the pager (I think) I get the following error about character 32. It works fine, but the error is a bit annoying. > ?version sh: invalid character 32 in exportstr for export R_NSIZE sh: invalid character 32 in exportstr for export R_VSIZE R.Version package:base R Documentation (and then the

Dear R users we're having a problem reading a largish data file using read.table(). The file consists of 175000 lines of 4 floating pt numbers. Here's what happens: > dat_read.table('sst.dat') Error: memory exhausted (This is line 358 of src/main/memory.c). Cutting down the file to around 15000 lines allows read.table() to work OK. I edited the memory limits in Platform.h

This example from the INSTALL help seems to be broken in R 0.90.1 (on Solaris): gilp/dse : R CMD check --help Usage: R CMD check [options] [-l lib] pkg_1 ... pkg_n I'm trying to figure out how to request more nsize and vsize when using R CMD check.

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? Paul Gilbert

Full_Name: Laurent Gautier Version: 0.65.0 OS: mips SGI-Irix 6.5 Submission from: (NULL) (195.110.4.98) Using R through emacs with ess5.1.8, I cannot set R workspace (--vsize and --nsize). So far I was using R0.64.2 without such a problem. I am aware my bug report is a bit light, but just let me know if anything I could do with my R and emacs would be of any help for\ specifying better what is

This is my first question to this list and possibly a bit dumb, but anyway: Can anybody tell me, where, e.g. in the "unix" reference release a DEFINITION of char * R_Home can be found? Via Defn.h the "extern" DECLARATION is everywhere, but when I derived a somewhat other main() program my linker complained about the missing definition. Thomas Hoffmann.

Hi, The Gnome version now compiles, and it should also be working (at least as much as it ever has). I've changed Makefile.in to the new system, which is very cool. What I want to work on now is: - Graphics. I want to move to the Gnome canvas for this, which should be reasonably easy. This will give us rotated text (which I never got going properly before) and the option for

Hi All, This is a very important issue. It would be very sad to leave most users unaware of a free speedup of this size. These options don't appear in the R --help output. They really should be added there. Additionally, if the garbage collector is working very hard, might it emit a note about better setting for these variables? It's not really my place to comment on design philosophy,

Hi Folks, I loaded a couple of quite large data sets into an R session and then quit (after saving the image). Now I get: Error: a read error occured Fatal error: unable to restore saved data (remove .RData or increase memory) after trying to start my R session using something like: R --vsize XXX --nsize 1000000 For any value of XXX (I went up to 300 or 400, which is as high as I could go.

Hi, I have gnuwin32 (b18) and the rw0613b.zip version of R.

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.

Hello R Developers, This is my first foray into using c-code with R, so please forgive my foolishness. I had a look at the archives and did not find anything on this, so hopefully I am not doubling up. I have tried to use R cmd to create an object file from the odesolve dynload example. I am using windows and have just installed rtools, and have the latest version of stable R (2..7.2). This is

It does, at least for a while. But when various more or less well behaved programs enter the scene (harddisk) things changed, at least for me. Reinstallation of R or windows didn't help, and I did not want to start again from scratch with a reformat. I used rw0613. -----Oprindelig meddelelse----- Fra: Douglas Steele <Douglas at dsteele.demon.co.uk> Til: r-help at stat.math.ethz.ch
