Hi all, I'm on a Linux server with 48Gb RAM. I did the following:
x <- big.matrix(nrow=20000,ncol=500000,type='short',init=0,dimnames=list(1:20000,1:500000)) #Gets around the 2^31 issue - yeah! in Unix, when I hit the "top" command, I see R is taking up about 18Gb RAM, even though the object x is 0 bytes in R. That's fine: that's how bigmemory is supposed to work I guess. My question is how do I return that RAM to the system once I don't want to use x any more? E.g., rm(x) then "top" in Unix, I expect that my RAM footprint is back ~0, but it remains at 18Gb. How do I return RAM to the system? Thanks, Matt -- Matthew C Keller Asst.
