I may seen somewhere that OSX has a "per process" limit of ~1.5GB max
RAM,
I think that WinXP has a limit on 2GB RAM,
In Linux, I believe a process can take ~4GB, more on x86-64 platforms
either directly or tweaking some option in the kernel,
Not sure though, I'm pretty sure someone else can give a clearer picture
on this,
Albert.

Hi all, Sorry if this is a dumb question, but I am on 10.4 with R2.2, and when loading a big text file (~500MB) with scan(file, what=character) I am throwing malloc errors that say I am out of memory...I have 5GB on this machine, and Activity Monitor tells me R is only up to ~1.84GB both times this has happened (running from terminal)... I am wondering why this is happening when I still have >2GB of free memory waiting to be used...? Any advice would be much obliged, Ken
