Try this xyplot.zoo lattice graph. Time series are represented in columns so we transpose the data and convert it to zoo. The screen= argument available in xyplot.zoo groups series into panels: Lines <- "plant,aphid,1,2,3,4 pumpkin,1-2,0.065566,0.057844,0.08,0.086879 pumpkin,1-3,0.107612,0.097272,0.11663,0.160499 squash,1-4,0.126939,0.115003,0.140275,0.188829" library(zoo) library(lattice) DF <- read.csv(text = Lines) z <- zoo(t(DF[3:6])) colnames(z) <- DF$aphid xyplot(z, screen = DF$plant) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ 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.
