Hi,
How can I add legends in the xyplot function, in the lattice library?
Here is a simulation example:
x - runif(90)
z - sample(1:3, 90, rep=T)
y - rnorm(90, mean = x^2 + z, sd=1)
.
Can someone give me a simple example or show how to do this for my example?
Thanks very much,
Ravi.

make it work. In particular, I do not understand how to use legend along
with the key argument. For my example, I would like to have a legend box
