[R] Saving graphs in formats other than PDF?

[Jim and Chana Milks]

I am running R 2.01 on Mac OS 10.3.7.  Whenever I save graphs, they are
saved as PDF files.  Are there any other file formats to which I could save
my graphs.  I would like to directly export my graphs to MS Word, if
possible.

Thank you in advance.
