Probably - but it requires a lot of work, because ggplot2 doesn't
currently support circular scales, which is what you really

Hi Hadley,
That solved a lot of problems. Thanks!
Do you get a vertically oriented bar? Here I get 15 bars with a space
where the north bar, the 16th bar, should be.
All the best,

Hi Thomas,
Ok, the key thing that you were missing was:
scale_x_continuous(limits = c(0, 360))
Since you don't have any data at 0, and because ggplot2 doesn't know
that your variable had intrinsic meaning as a degree, it was starting
zero degrees at 22.5.
A few other tweaks below:

Aloha Hadley,
Thanks very much for ggplot. It's a terrific piece of work.
Specifying width = 1 in the call to geom_bar didn't change the
orientation of the coordinates. If you run the example, you'll see
that 100 is horizontal, where 90 would be on the compass.
Here is a reproducible e
Hi Thomas,
I suspect you want geom_bar(stat = "identity", width = 1), but it's
hard to be sure without a reproducible example.

Aloha all,
I love using ggplot. It took a while to get used to the grammar of
graphics, but it is starting to get easy now that I am thinking in a
more structured way.
A question. I'm making a wind rose that I'd like to be oriented with
due north straight up. I've discovered that the ori
