Well, unless you intend installing a 64 bit distro, there's no point in worrying about a upgrade path from 4 Gig of RAM
I'm running a 64-bit Fedora at the moment, for Vmware/Virtualbox it makes sense. I have 6Gb of memory.
Assuming hardware supports it (most new hardware will, surely) is there any good reason *not* to install a 64-bit O/S now?
The R documentation ("R Installation and Administration", Section "8 Choosing between 32- and 64-bit builds", see http://cran.r-project.org/doc/manuals/R-admin.html) says that for a given amount of data, you'll need less memory on 32 bit due to smaller pointer sizes, and that for the same reason, R can be faster on a 32 bit OS.
Does anyone here have practical experience with this?
