Dear R-help list,
I am just trying to increase my memory for R, but for some reason I
cannot really increase the memory size as much as I would like. I
have 3 GB of RAM on a Windows XP (R 2.8.1)
memory.size()
[1] 879.4667
memory.size(T)
[1] 1162.75
memory.limit()
[1] 3072
gc()
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 421697 11.3 1476915 39.5 1476915 39.5
Vcells 45503399 347.2 147241270 1123.4 147023097 1121.7
Yes, so you didn't use all the memory available: but to do so you
probably need very many small objects.
What am I missing?
The rw-FAQ? Setting the limit to more than your address space (which
you probably) have does not increase the latter. Of your 3GB, Windows
normally only gives 2GB to any one process. See the rw-FAQ for the
exceptions.
Also ?'Memory-limits'.
With many thanks and best regards,
Stefan
