Hi Eddie, I've been on a role with the iris data, so I figure why stop. Assuming that one variable is a factor, you can easily reverse it, and if you want fine tuned control, then just reorder the levels. Here is an example:
dat <- iris boxplot(Sepal.Length ~ Species, data = dat) boxplot(Sepal.Length ~ rev(Species), data = dat) # They had been ordered alphabetically, now I am changing them dat$Species <- factor(dat$Species, levels = c("versicolor", "virginica", "setosa"), labels = c("versicolor", "virginica", "setosa")) boxplot(Sepal.Length ~ Species, data = dat) Cheers, Josh On Mon, Sep 27, 2010 at 12:59 PM, Hughes, Ed <ehug...@conshelf.com> wrote: > Hello All, > > > > I noticed when I generated some boxplots, the data is presented in > alphabetical order along the x-axis (the data in this case was the four > quandrants of a sample area (NE,NW, SE, SW) that was my first column of > data). Is there a way to have R plot the data in a different order?
