Dear Sandy,
Have a look at the position argument of geom_histogram.
ggplot(data=dafr, aes(x = d1, fill=d2)) + geom_histogram(binwidth = 1,
position = position_dodge())
gg
You may find it easier to use a frequency polygon, geom = "freqpoly".

Dear Sandy,
Have a look at the position argument of geom_histogram.
ggplot(data=dafr, aes(x = d1, fill=d2)) + geom_histogram(binwidth = 1,
position = position_dodge())
ggplot(data=dafr, aes(x = d1, fill=d2)) + geom_histogram(binwidth = 1,
position = position_dodge(width = 0.5), alpha = 0.5)

There is a google group dedicated to ggplot2. It might be worth making a post
there:
