Re: [R] Combining ggplot2 objects and/or extracting layers

Hi Marshall, It sounds like an interesting idea. I would approach it in a slightly different way. I'd recommending writing a function that returns a geom_bar object - that way you can easily add it on to any existing plot, specifying the appropriate parameters. If you just wanted to plot that l
