In library MASS in the V&R bundle. Multiple CA and lots of plots as well.

hearing from you.

Fionn M. is male.  There is a pre-compiled Windows version of that library
on statlib in DOS/S/SWin (AFAIK: did you check?), or, nearer to you, at

http://www.stats.ox.ac.uk/pub/SWin

But correspondence analysis is an elementary operation and is at
least as easily programmed in S.

The precompiled version runs on both.
