Hi all,
I'm running an analysis with the random forest tool. It's being applied to a
data matrix of ~60,000 rows and between about 40 and 200 columns. I get the
same error with all of the data files (Cannot allocate vector of size
428.5MB).
I found dozens of threads regarding this problem, but they never seem to be
concluded. Usually the OP is directed to the memory allocation help file
(which I haven't understood the solution for linux), and the last post is
the OP saying they haven't sorted out their problem yet.
I'm running on a LINUX machine wtih 64GB RAM, so it's not a problem with
lack of system resources.
Can anyone tell me how I can get R to allocate larger vectors on Linux?
1. Check how much memory R used at the point the error message appeared.
If it is round about 60 Gb, you know that it is lack of resources - for
the given problem. If it is much less (around 2Gb), you might have a
32-bit R binary or you have some memory quota for your process.

Many thanks,
