Re: [R] Assigning line colors in xyplot
Thanks to Deepayan and Hadley for their help, both solutions work, not only for the example below, but also for my real data set that I'm about to analyze.

Hi Christof, You can do this in ggplot, with one exception: install.packages(ggplot2) library(ggplot2) qplot(x, y, data=tmp, facets = . ~ g, geom=line, colour=f) Unfortunately I don't yet have an implementation of facetting that works like lattice, wrapping the line of plots in to 2d dimensions.
