[R] ggplot2 histograms

2010-11-30 Thread Small Sandy (NHS Greater Glasgow & Clyde)
Hi With ggplot2 I can very easily create beautiful histograms but I would like to put two histograms on the same plot. The histograms may be over-lapping. When they are overlapping the bars are shown on top of each other (so that the overall height is the sum of the two). Is there any way to get
