[R] Change pattern in histograms in ggplot2

Hi, I am wondering if there is a way to change the pattern of the fill in histogram in ggplot2? By default the fill is solid and I'd like to add some sort of pattern to make it more visible that these are different levels of a factor. Thanks! Chris [[alternative HTML version deleted]]

There are a number of discussion threads on the google groups ggplot2 page: here are two of them. http://groups.google.com/group/ggplot2/browse_thread/thread/ca546f7f4d636deb/e0763a54b7735c35?lnk=gstq=fill+pattern#e0763a54b7735c35
