The `legend` function is used with base graphics plotting (as is the par function).
David, And that's how I used it before so it is the wrong template for this plot. Mea culpa!
I think you might first read ?Lattice since it makes reference to the fact that you can update trellis structures after they have been created.
That's what I was trying to do but with the incorrect name.
The commands to add "legend" features to lattice plots are found under the argument items with names "key". Search in ?xyplot for the strings 'legend' and 'key'. It would probably be easier to incorporate these in a new plot call. There are several examples (well, four anyway) at the ?xyplot page. Since you mentioned having Sarkar's book, the place to look for more examples is chapter 9 "Labels and Legends".
I did read that but mis-applied what I read. Tried auto.key but that did not work as desired. Now I know to learn how to apply 'key'.
