I have a general question about R's usage or memory and what limits
exist on the size of datasets it can deal with.
My understanding was that all object in a session are held in memory.
This implies that you're limited in the size of datasets that you can
process by the amount of memory you've got access to (be it physical or
paging). Is this true? Or does R store objects on disk and page them in
as parts are needed in the way that SAS does?
Are there 64 bit versions of R that can therefore deal with much larger
objects?
Many thanks.
