You are on Windows, right?

See ?memory.limit

You cannot say "Inf", but memory.limit(4000) sets it to 4Gb which you 
won't reach with a 32bit machine anyway.

Say you are on a 32bit machine with 512Mb of RAM, you certainly do not 
want that R accesses much more than 512Mb for itself, in order to 
prevent too much swapping. And that's what R chooses for you.
