An R-News or J. of Statistical Software note titled, "Getting to the Source
of the Problem" detailing the basic strategies for these adventures in the
new world of S4 methods and namespaces would be very useful.

That's because `assist' has a namespace:

    Non-visible functions are asterisked

Use either assist:::predict.ssr or getAnywhere("predict.ssr").

Oh yes. The "load package" under the "packages menu" in the
Windows version
does that. To check I typed "library(assist)" after starting R. Same
behavior, ssr is found, but others like predict.ssr, and
plot.ssr, give a
"not found" message.

Thanks for the suggestion.

Mike
