I have found a bug in a package that wraps a function around ggplot to plot some graphs. It's a 400+ line function that will take a bit of time to look through, but it shouldn't be hard to fix; anyone familiar with ggplot should be able to identify this pretty easy. See odesk.txt for a link to the package function, function call, and an example data set. The problem is that when graphing using the ggplot wrapper in the rms package the multiplots do not line up and the legend colors are different. It seems as if the first plot gets a different color than the others and the legend colors only apply to the first plot.
