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)
library(lattice)
trellis.par.set(col.whitebg())
xyplot(y ~x, groups=as.factor(z), type = c('p', 'smooth'), span
= .67)
Thanks in advance,
Ravi.

See ?xyplot and its argument "legend".
