It would be very useful if you would post some information about what
exactly you are doing. There si something with the size of the data
object you are processing ('str' would help us understand it) and then
a portion of the script (both before and after the error message) so
we can understand the transformation that you are doing. It is very
easy to generate a similar message:
> x <- matrix(0,20000, 20000)
Error: cannot allocate vector of size 3.0 Gb
but unless you know the context, it is almost impossible to give
advice. It also depends on if you are in some function calls were
copies of objects may have been made, etc.
