[R] error msg for vector of size

[Ott Toomet]

Hello,

It looks like your memory has become fragmented (there are several MB
free but not a single 2 MB chunk. 

If this is the case, you may consider:

1) save your data, exit R, start it again and continue.  It should
   free all the memory, occupied by R, and hopefully allocate it
   better next time.

2) Use unix/linux.  There are rumours that unix has better memory
   management than windows (your mail was sent from windows).  

3) Dont start other programs while R is running.  Keep the number of
   running programs/precesses to minimum.  They may be part of the
   reason of memory fragmentation.

4) Try with subsets of your data, split your data into separate
   indipendent subsets (if you can) etc...

Perhaps it helps.

Ott
