[R] R memory question (fwd)

[Jing Wu]

Dear all,

I am trying to use rlm in MASS to do an analysis on a 21632*12 matrix.
There are 4  factors A,D,V,G; A of level 6, D of level 2, V of level 2, G
of level 21632, and 21632*12 observations Y. The data format is
A D V G Y
1 1 1 1 0.1
1 1 1 2 0.2
...

The command I use is rlm(Y~A+D+V*G,data=data.dat)
 I got the same error message:
Error in rep(data, t1) : cannot allocate vector of length 467748756

I am using a unix machine of 4GM memory. I would like to know if R is
using all the available memory and/or how much memory R would use to
handle is data set.


Jing
