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....

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: http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=123 Anyone have any ideas.

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 norman -- %>>> "".join( [

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
