I am using ESS on a unix system for my analysis. My R environment
contains a 90118 by 94 dataframe. I am trying to calculate the mean of a
column in this data frame and I am getting the following error:
Error: can not allocate a vector of size 704 Kb
I have tried
and this does not help.
when I call gc() this is what is returned
used (Mb) gc trigger (Mb)
Ncells 1178845 31.5 2564037 68.5
Vcells 11666683 89.1 38686231 295.2
I tried calling mem.limits(nsize=1000000000000). Any value for vsize
gives an NA error, and when I recall gc() the limit for Vcells is NA.
There is more than enough memory available on the Unix machine, when I
call top I am using 0.0% of the memory and the other handful of users are
using about 10% all together. I have increased my user memory limit
and that still did not help (I found an email in R-help archives
suggesting this). It seems to me that 704Kb is a rather small size to
give an error and it appears to be available on the system.
