Re: [R] Yet another memory limit problem
Thanks for everyones help - mydat was not what I thought it was. str(mydat) showed: $ Date : Factor w/ 1504 levels ,2002-11-22,..: 295 295 295 295 295 295 295 295 295 295 ... $ Time : Factor w/ 72447 levels ,00:00:00,..: 15423 15470 15509 17112 17136 17159 17209 17239 17266 21527 ... I didn't properly convert date and time using chron. Not sure how R plots factor levels, but obviously it has problems with it!

[R] Yet another memory limit problem
Dear List, I have read and read and still don't get why I am getting a memory issue. I am using a Samsung PC running Windows 7. I have set memory in the target field: C:\Program Files (x86)\R\R-2.11.1\bin\Rgui.exe --max-mem-size=3G But when I try a simple plot I get: plot(mydat$Date,mydat$Time) Error: cannot allocate vector of size 831.3 Mb memory.size() [1] 2099.61 memory.limit() [1] 3583 dim(mydat) [1] 245 9 I would appreciate some help. I think I set the target field correctly, both memory.size and memory.limit indicate I have over 2G of memory, yet I can't allocate 831.3Mb? It just doesn't make sense to me.
