R help - Sep 2009 - releasing memory when using the ncdf package

Hello,

I'm running R 2.7.2 in a windows XP environment and I run the
following in an R console:

library(ncdf)
nc <-open.ncdf('c:/file.nc')
aa <- get.var.ncdf(nc,'var1')

This works fine, but 'aa' takes up about 100mb and I want to release
the memory after using it.  I try:

rm(aa)
close.ncdf(nc)

and look at Windows Task Manager, but the memory hasn't been released.
 Do you know what I should do to release the memory?  Thanks in
advance.

eric

Hi,

Try the gc() command.

cheers,
Paul
