You must be using Windows, without telling us. The rw-FAQ tells you the 
answer, as well as the help page that message refers to.  It's better for 
you that you learn to use these resources than ask 2000 people to read 
them for you.

You may also need to get a bigger computer, since you are trying to create 
a single object bigger than your computer's RAM memory and a high 
proportion of the address space of a Windows machine.  It might be more 
sensible to ask your more senior colleagues for advice on your statistical 
computing and see if you can avoid this computation.

which asks you to read the rw-FAQ before posting.
