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...

lme weights glht
Dear R-user
I used lme to fit a linear mixed model inlcuding weights=varPower().
Additionally I wanted to use glht to calculate Tukey-Kramer multiple
comparision.
error:
> glht(modelF, linfct=mcp(Species="Tukey"))
Error in glht.matrix(model = list(modelStruct = list(reStruct =
list(SubPlot = -0.305856275920955, :
?ncol(linfct)? is not equal to ?length(coef(model))?

Frequency table
...d_freq_t <- t(Wind_freq) ## transpose it to be in the same format as
the data above
but I need to incorporate the speed values and have a table like the
following:
1 2 3 4 5 6 .... 36
0-9
10-19
20-29
30-39
40-49
50+
The final table will be used in the rosavent function to produce a wind rose
diagram just like in this example:

Anyone have any ideas. Thanks.

Draw Polygon with a Circular Side
Hello Friends!!!
I would want draw a circular histogram, and I would like draw a polygon with
a circular side. This is easy if I use the functions polygon and arc, but I
want that the polygon with a circular side have background colour. The
polygon created with function polygon can have background colour, but the
surface created with function arc can?t have background colour.
How I could create a

representing wind date using windrose
hello,
i am new to R and want to use it for a small project to draw a wind
data from a microclimate datasource, can someone give me an example of
how i can represent this in a neat way?
for example, i have:
speed, direction
0.3,NNE
0.45,NNE
0.32,NE
0.28,N
0.30,NE
how do i put this data to get a windrose graph?
many thanks

Wind-data analysis with R?
Hello,
are there people outside who use R for analysis of wind-measurement data
(meteorological or for planning of wind power stations)?
Are there already scripts/modules available for analysing and
displaying/plotting wind data in the way it is done in projection/planning
of wind power stations?
If not, would it be of interest to use R for this, and therefore
adapt data-logger output to R (by
