I have a 64-bit windows box -
Intel Xeon CPU E7340 @ 2.4GHz 31.9GB of RAM
I have R 2.11.1 (64bit) running on it.
My csv data is 3.6 GB (with about 15 million obs, 120 variables.)
------------------------------------------------
I have successfully imported the data above into R. No problem.
Now I am trying to run 'rpart' on my data. But I got the following error :
Error: cannot allocate vector of size 53.5 Mb
In addition: Warning messages:
1: In lapply(x, "is.na") :
Reached total allocation of 32764Mb: see help(memory.size)
2: In lapply(x, "is.na") :

Can anybody give me a hint on how to solve this?
Thanks!
