R help - Mar 2010 - R Cmdr memory

Hi,

I keep getting this error in console. but I have 30G of RAM:

Error: cannot allocate vector of size 154.3 Mb

Is there some way to tell it I have more memory available?

I am on Windows XP 64 bit

But you are probably using 32 bit R.

You could try running this code. I copied if from a posting on r-help,  
but regret that I did not insert a comment to remind me who posted it.

getsizes <- function() {z <- sapply(ls(envir=globalenv()),
                                     function(x) object.size(get(x)))
  (tmp <- as.matrix(rev(sort(z))[1:10]))  }

I had the same sort of question so many times that I added it to  
my .Rprofile

Is there a 64 bit R - and where can I get hold of it for Windows please?

Your sizes function is useful thanks - but is there some R parameter to
allow maximum usage of memory?

For Windows XP?, Not that I know of. There are proprietary versions  
for Vista and I believe Professor Ripley is working on an experimental  
version for the 64 bit versions of Windows.

Read the Windows FAQ and seearch on "memory".
