Thanks David and everyone for the help.   I do see "x12" under the 
RsiteSearch and will test it to see if it works for what I need to do.

Happy new year!

Tony

Agree that is sensible for general questions, but it will not find 
anything very specialized because it only searches installed packages. 
So unless the user has already installed packages with key words that 
match the search terms, it will fail.

I found the x12 package listing with RSiteSearch("x12") at the R 
console. I thought that strategy would have been described in 
Introduction to R but when I tried I did not find it there.
