The equivalent function to "dotplot" in Splus is (and has always been)
called "dotchart".  The name in Cleveland's "Elements of Graphing Data"
is "Dot Chart".  I just mis-remembered the name when I wrote the R
function ... (Sorry! I know name changes are a pain.).

The Lattice functions will provide generalized functionality for
dotplot and stripplot -- i.e. they will serve the same pupose as the
existing functions, but they will do a lot more.

The point in marking the present functions deprecated is to signal that
the change is coming.  You will be able to use the present functions
under the old names by doing
	dotplot <- dotchart
	stripplot <- stripchart
but I think you will like the new stuff.
