Hi
If you use the lattice package and not resort to other packages read the ?
xyplot carefully
There are several ways to put a key in the graph including auto.key if you
want something simple ie default
The examples at the bottom give some ideas
If you want something special you can use key = list(...) eg
key = list(text = list(labels = LETTERS[1:3], cex =
c(1,1,1) ),
title = "Farm", cex.title = 1,
points = list(pch = c(20,20,3),
col = c("black","grey","grey")),
lines = list(lwd = c(2,1,2),
lty = c(1,1,1),
col = c("black","black","grey80")),
space = "bottom"),
which gives 3 columns: text points and lines.
