rose-diagram

I created a rose diagram of aspects in degrees for location data using the 'circular' package in R and the rose.diag function, with basic aspects of N, NE, E, etc., for a total of 8 bins. However, the bins do not straddle the aspects. In other words, the first bin goes from 0-45, the 2nd from 45 to 90, and so on, which is pooling the aspect data in strange ways. Is there any way to shift the bins so 0, 45, 90, etc are the center of the bins, instead of the edges? rose.diag(Degrees$Degrees, bins=8,zero=pi/2, units = 'degrees', rotation='clock') I think Ben is right that it cannot be done easily

I am looking for good R code (or package) that uses ggplot2 to create wind roses that show the frequency, magnitude and direction of winds. I'm particularly interested in ggplot2 as building the plot that way gives me the chance to leverage the rest of the functionality in there. Test data Download a year of weather data from the 80-m level on the National Wind Technology's "M2" tower. This link will create a .csv file that is automatically downloaded. You need to find that file (it's called "20130101.csv"), and read it in. # read in a data file data.in <- read.csv(file = "A:/drive/somehwere
