Re: [R] Extracting wind direction and wind speed from wind rose plot

I am curious what you mean by "having a graph." If you mean something drawn on paper or an image on your screen, then extracting specific data at various points is an effort, perhaps more so if a wind rose plot does not contain all you need. If you have something like a ggplot2 object, it tends to

Re: [R] Extracting wind direction and wind speed from wind rose plot
