[R] unlist kills R

[Manuel Gutierrez]

When I try to unlist a very large list, R is killed
without any other warning:
A<-as.list(as.data.frame(matrix(1:21639744,nrow=3578,ncol=6048)))
with 
AA<-unlist(A)
or
AA<-c(A,recursive=TRUE)
I get a 
R terminado (killed)
and the end of the session.
I think I'll need to get more RAM (now 1Gb, any other
solutions welcomed) to be able to do this but,
shouldn't I get a more gentle warning than the kill
message?
Thanks,
Manuel
