Hi, Matt, Yes. Try this: my.data <- data.frame(x = 1:10, y1 = 1:10, y2 = 11:20) xyplot(y1 + y2 ~ x, my.data) ## or if you want y1,y2 in panels xyplot(y1 + y2 ~ x, my.data, outer = TRUE) HTH, --sundar ______________________________________________ R-help@stat.math.ethz.ch 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.
