similar to: Wind-data analysis with R?

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( [

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

Greetings! I'm having an issue with the windrose produced by the windrose function from the circular package. For our weather stations in North Carolina I'm helping with a script which takes hourly wind speed and direction data to create windroses for our end users. One of the stations in the mountains frequently reaches wind speed of 40 to 60 mph and in storms can reach wind speed over

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

Dear list, I trying to make a wind rose plot whit the command oz.windrose, from plotrix package. My data, a matrix of percentages with the rows representing speed ranges and the columns indicating wind directions was generated using bin.wind.records command from same package: [,1] [,2] [,3] [,4] [,5] [,6] [,7] [1,] 0.4405286 0.0000000 0.1468429 0.4405286 0.4405286

I'm having trouble understanding the output from as.windrose(). For one thing, data on a boundary between sectors seem to be left out of the counts. I assume that explains the missing point in the output below (angle 45). Shouldn't one side of each sector interval be open, to include values such as my 45 in the example? Also, why does the angle 180 in my input apparently not result in

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. Karl Ropkins,

Hi All - I have been using the windrose function found in the circular library to create great looking windroses.  But the dashed, circular percent interval lines that indicate the frequency at which each "pedal" occurs are not evenly spaced (the corresponding parameter is "cir.ind").  That is, the 5% interval closest to the heart of the windrose is wider than the 5-10 chuck,

Full_Name: Allyson Williams Version: 2.1.1 OS: Windows XP Submission from: (NULL) (203.25.1.208) I'm using the 'Circular' package to plot windroses. I think the output table (see out2$table below) is incorrect when using different rotations. More precisely, when a rotation is used for the plot, the output table stuffs up. This example is from the code in the help notes, although the

Hello, I'm trying to make a table like windfreq.dat in the rose diagram example of the climatol package. It looks like: N NNE NE ENE E ESE SE SSE S SSW SW WSW W WNW NW NNW 0-3 59 48 75 90 71 15 10 11 14 20 22 22 24 15 19 33 3-6 3 6 29 42 11 3 4 3 9 50 67 28

Dear R Gurus, I spent some time in looking for help but didn't find a way to do what I want. I do have a vector (in Degrees) containing of 360 elements, one element per degree on a circle.

Hello, I have strings with date-/time-data from a logfile. For a sort-by-time (and other time-related analysis) I need something to convert the times to the Unix-epoche-time (better also with parts of seconds). Is there something that does that job (or a similar conversion) in R? TIA, Oliver Bandel

Folks, I've scoured the website and googled, but can't find a definitive answer: What's the difference? OK, the site says 1.4.26.1 is latest stable. Site also says 1.6.2.0-beta4 is latest beta. So what are the others? TIA, David A. Bandel -- Focus on the dream, not the competition. - Nemesis Air Racing Team motto Visit my blog at:

Hi List, I am trying to create a spatial representation of some wind data. I have the season, frequency, strength and direction of the wind from 10 different locations, the coverage of the area that I am interested in is not 100% there are small gaps in my coverage due to the location of the weather stations. I am trying to create a series of wind maps e.g. the Prevailing Winds, the maximum
