similar to: Frequency table

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

I am trying to extract the shape and scale parameters of a wind speed distribution for different sites. I can do this in a clunky way, but I was hoping to find a way using data.table or plyr. However, when I try I am met with the following: set.seed(144) weib.dist<-rweibull(10000,shape=3,scale=8) weib.test<-data.table(cbind(1:10,weib.dist))

Hello, I've run into a problem which is both maddening and rather hard to replicate, therefore I wondered if someone might know of a plausible explanation for it. I couldn't find anything in the archives, though maybe I'm searching for the wrong thing. I'm calling some C code using .C, and get the vector I'm interested in back as the 7th location in the returned list.

I tried the following ordered logistic regression in R: mod1 <- polr(altitude~sp + wind_dir + wind_speed + hr, data=altioot) But when I asked The summary of my regression I got the folloing error message: > summary (mod1) Re-fitting to get Hessian Error in optim(start, fmin, gmin, method = "BFGS", hessian = Hess, ...) : the initial value of 'vmin' is not

Dear all, I'm wondering if there exist vectorized forms of 'isTRUE()', 'identical()' and 'all.equal()'. My problem is that I wish to test if each element of a vector is equal to a particular value (or numerically close), whilst dealing carefully with NAs and so on. However, using sapply() with identical() is very slow because it makes so many separate function calls:

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( [

Hi, I'd like to plot in in polar coordinates a line which is given as a vector of lengths and angles. library("plotrix")

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

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

I have a set of wind speeds read at different locations. The data is a data frame with two columns: site and wind speed. I want to split the data on site and call a function to find the shape and scale parameters of a weibull distribution fit. The end result is a plot with x-axis = shape and y-axis = scale. Currently my code looks like: fit_wind_speed<-function(x){

O'Reilly ang "Teach yourself samba in 24 hours" I have tried to get swat up running and configure samba therefrom.

Previously the file plugin supported ‘rdelay’ and ‘wdelay’ parameters for injecting delays (for testing) into read and write requests. This moves the functionality to a new delay filter so that it can be used with any plugin. --- TODO | 3 - configure.ac | 1 + filters/Makefile.am | 1 + filters/delay/Makefile.am

Hello, This seems like a fairly elementary question, but I couldn't seem to find the answer anywhere online. Where can I find code which is called with .Internal? ?Specifically, the R function colSums() calls an internal function with the same name (I presume a C function), and I'd like to see how it works. I've searched through the header files in R-2.x.x/include/ (Windows

The report on R_help about problems loading package irr (in a UTF-8 locale, it seemed) prompted me to look a little deeper. There are quite a few packages with Latin-1 chars in their .R files, and a couple in UTF-8. Apart from non-ASCII chars in comments, this is a problem as the code concerned cannot be represented in some locales R runs in (for example Japanese on Windows). It happens
