Dear R-experts, I want to assign different colors to groups of points, lines and segments in a plot.
I have a vector(dat$tx) that is going to have a different number of levels every time the user wants to plot a set of data. The number of lines is going to be equal to the number of levels of the vector mentioned. What I have so far is this: plot(1,1,type="n") for (i in dat$tx) { points(summ$timep[summ$tx==i],summ$mn[summ$tx==i]) lines(summ$timep[summ$tx==i],summ$mn[summ$tx==i]) } How can I assign different colors to the points and lines? Thank you in advance for any help, Judith ____________________________________________________________________________________ Be a better friend, newshound, and ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
