R help - Oct 2010 - plotting wind rose data (Karl Ropkins)

David,

Following on from Jim Lemon's suggest that polar plots might be more what
you need, there are both wind rose and polar plot functions in the openair
package that might be of use (particularly windRose and polarFreq). They will
not do everthing you are after without some careful conditioning or extra work
with latticeExtra, but could get you some of the way there.

Hi David,
While there are several packages that include plotting routines for wind
roses, it looks to me as though you want to define a small number of
vectors representing prevailing wind, etc., possible overlaying these on
a plot. That might be a job for a circular plotting routine (e.g.
polar.plot) rather than a wind rose.

Hi Karl,
There is an example of using Deducer's with ggplot2 to produce a rose plot
(including a video of use), I thought you might find it useful:
