[R] How to add legend to a dotplot

[Jim Lemon]

Hi Hanna,
That is because "dotplot" is a lattice graphics function and "legend"
is a base graphics function. There are two things you can do to fix
this. One is to use the "dotchart" function in base graphics. The
other is to use simpleKey in the latticeExtra package for the legend.
