Dear Prof. Ripley,
Thanks a lot. I've just looked at Rcompression and it seems to do
exactly what I need, though it requires having zlib and bzip2
installed (and I am not sure if this will deter some windows users).
I'll also check connections.c, which might be a way to go, or else
wait for the re

One solution is likely to be the Omegahat package Rcompression.
Otherwise, R does have internal facilities to do internal (gzip)
compression and decompression (e.g. see the end of
src/main/connections.c), and you could make creative use of serialization
to do the compression.

Dear All,
I'd like to be able to have R store (in a list component) a compressed
data set, and then write it out uncompressed. gzcon and gzfile work in
exactly the opposite direction. What would be a good way to handle
this?
