I normally use ggplot2, and I know how to plot multiple datasets by simply + a new geom with a different data option, but usually in these case my different datasets have had the same x and y axes. Can I add a new x axis to the top of the plot in ggplot2 or one of the other graphics packages? library(ggplot2) library(gridExtra) x <- qplot(mpg, disp, data = mtcars) y <- qplot(hp, wt, data = mtcars) grid.arrange(x,y) -- David Winsemius Alameda, CA, USA ______________________________________________ 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. ______________________________________________ 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.
