No. See ?"Memory-limits".
However, you would need a lot more than 5GB of RAM (say 64GB) for R to run
comfortably with the size of object you are trying to create (16GB for a
real-valued matrix). One day when the R developers are using such systems
we will begin to address the issue (but it will require a lot of work by
package maintainers if we do). I think it was three years ago I
estimated that point as being five years away -- and 64-bit versions of R
are still a small minority.

PLEASE do as you were asked in the posting guide and send well-formated
plain text only. I've deleted tens of unneeded blank lines in your
posting which did not even fit on one screen.
