Hi all, I have a data frame like this:
DF <- data.frame(x = rnorm(10), y = rnorm(10), gr = rep(1:5, 2)) and I make the following xy-plot: library(lattice) xyplot(y ~ x, data = DF, groups = gr, type = "b", col = 1) Is it possible that the two points that belong to the same group specified by DF$gr to have a different color -- that is for each pair of points connected by the line, I want one to be black and the other red. I tried: xyplot(y ~ x, data = DF, groups = gr, type = "b", col = 1:2) but it doen't work. Is there any solution for this?? Thanks a lot!
