Hello all, I'm working with a large data-set, and upgraded my RAM to 4GB to help with the mem use.
I've got a 32bit kernel with 64GB memory support compiled in. gnome-system-monitor and free both show the full 4GB as being available. In R I was doing some processing and I got the following message (when collecting 100 307200*8 dataframes into a single data-frame (for plotting): Error: cannot allocate vector of size 2.3 Mb So I checked the R memory usage: $ ps -C R -o size SZ 3102548 I tried removing some objects and running gc() R then shows much less memory being used: $ ps -C R -o size SZ 2732124 Which should give me an extra 300MB in R. I still get the same error about R being unable to allocate another 2.3MB. I deleted well over 2.3MB of objects... Any suggestions as to get around this? Is the only way to use all 4GB in R to use a 64bit kernel? Thanks all, B.
