It is nice to know that we anticipated your needs. It is actually even
easier. If you do (using the Rtools or other sources, or on a Unix-alike)
mv filename.RData.gz filename.RData
R will read the compressed file directly (you don't need to rename it, but
it helps keep things tidy).
[As an aside, I wonder whether compress=TRUE should not be the default for
binary save/save.image. It adds little time and may save a lot of disc
