I've searched the archives and read the xyplot help but can't figure out the 2 lattice questions below?
Consider: library(lattice) DF <- data.frame(x=rnorm(20), y=rnorm(20), g1=rep(letters[1:2], 10), g2=rep(LETTERS[1:2], each=10), g3=rep(rep(letters[3:4],each=5),2)) xyplot(y ~ x | g1 + g2, groups=g3, data=DF) 1) Is there a way to get one strip per row and column of panels as below instead of the default? _|__a__|__b__| | B | -- | A | 2) How do I control the text of the strips so that for instance instead of "a" and "b" it reads"g1=alpha", "g1=beta" where "alpha" and "beta" stand for the corresponding greek symbols? (my difficulty here is not with the plotmath symbols but with controlling the text of the strips directly from the call to xyplot and not by renaming the levels of g1) I'd appreciate any help!
