How do I put a legend for the grouping variable in the empty upper-
right panel?
See the help page for xyplot for an example using the iris data.
You just need to add something like
auto.key = list(x = .6, y = .7, corner = c(0, 0))
to your lattice call. See the 'key' entry on the ?xyplot page.
On my machine the default color scheme is TRUE, so the auto.key comes
out with colored circles. This incantation gets the key to match the
plotting symbols and lines:
xyplot(x~y|SP, data=data,groups=z, layout=c(2,3),
par.settings=simpleTheme(pch=1:4,lty=1:4,col='black'), type="b",
auto.key = list(x = .6, y = .7, lines=TRUE, corner = c(0, 0)) )
