As you can see, Prof. Friendly refers me to your site for an
executable version of vcd. I don't mean to be obtuse, but 15 minutes
spent exploring your site failed to locate a downloadable version of the
vcd package to which he referred.
I know plainly what this application can do. What I need to know is
how to obtain the application itself.
My thanks in advance for any help you can provide.

You can also carry out goodness of fit tests using the function goodfit
in the vcd package
for R (a free version of S/Splus),
