Hi: It's not a perfect solution, but an 'easy' way out is to recognize that some symbols are open and some are filled. If you want fill, use a filled symbol and then change the color.
p <- rep(16:18, 4) x<-c(1:12) y<-c(rpois(12,4)) grp<-c(rep(c(3,4), each=6)) z<-c(rep(c(1,2), each=6)) dd <- data.frame(x, y, grp, z, p) xyplot(y ~ x, data = dd, cex = 1.2, pch = dd$p, col = c('black', 'blue')[dd$z]) HTH, Dennis On Thu, Feb 10, 2011 at 1:21 PM, John Poulsen <jpoul...@whrc.org> wrote: > Hello, > > I am trying to make a xyplot plot with points that are different symbols.
