rosavent problem

I have a frequency table that I am trying to plot on a rose diagram
using
rosavent. I've set the table up by using this line:
Wind_freq_speed <- t(table(cut(Wind_Dir_vec, 0:36),
cut(Wind_Speed_vec,
seq(0, to=60, by=10))))
It produces the following table layout, which is consistent with the
rosavent example (windfreq.dat).
10 20 30 40 50 60 70... 360
0-10
10-20
20-30
30-40
40-50
50-60
However, when I use the rosavent command (i.e.
rosavent(Wind_freq_speed)),
it produces a rose diagram with my data plotted 6 times around the 360
degrees. I also get the following error:
Error in legend(-fmaxi - 2 * fint, fmaxi, fill = col, legend =
attr(frec, :
'legend' is of length 0
If you indicated what package that function was from, then I missed it. The thought did occur to me that maybe it was expecting arguments in radians since 2*pi is fairly close to 6.
