Hi.
I was not careful to 32bit very much.
You can expand memory for data to 2G by LDR_CNTRL.
It is as follows.
LDR_CNTRL="MAXDATA=0x10000000" 1 256 MB
LDR_CNTRL="MAXDATA=0x20000000" 2 512 MB
LDR_CNTRL="MAXDATA=0x30000000" 3 768 MB
LDR_CNTRL="MAXDATA=0x40000000" 4 1024 MB
LDR_CNTRL="MAXDATA=0x50000000" 5 1280 MB
LDR_CNTRL="MAXDATA=0x60000000" 6 1536 MB
LDR_CNTRL="MAXDATA=0x70000000" 7 1792 MB
LDR_CNTRL="MAXDATA=0x80000000" 8 2048 MB
try.
$ export LDR_CNTRL="MAXDATA=0x80000000"
$ R -q
> xx <- matrix(rep(1e+10,1e7),nrow=1e4,ncol=1e3)
> tmp.df <- as.data.frame(cbind(xx,xx,xx))
