Dear All,
I'm running the latest R on SUSE 10.0. After read in a huge data CDF file
I tried to process the only variable variable using the comands
aek<-open.ncdf('C:/Monthly/CRU/Crutmp Europe.CDF')
v1<-aek$var[[1]]
gugus<-get.var.ncdf(aek, v1)
But I can't because of this message
Error: cannot allocate vector of size 1215000 Kb
I'm now hoping for some help
Any tips to get out of it?
Thanks in advance.
john

R request 1.2Gb of RAM just for the very next step in get.var.ncdf()! You should probably reduce the data and work on subsets.

The memory.size() command provides the maximum amount of memory that can be allocated. The amount can be increased to for example 2 GB by the command: memory.size(size = 2048) On windows the max size is 2GB, I don't know how large it is on Linux. But I must agree with Uwe Ligges that it may be better to cut up your dataset. kind regards, Paul Hiemstra At 10:59 18-10-2006, John Kapsomenakis wrote:>Dear All, >I'm running the latest R on SUSE 10.0.
