Hello Josh, Thank you for the tip on the cut function. I'm new to R and have not come across this one yet. I'll give it a go.
Regarding the rationale for segmenting the wind direction, I have not come across any theory to drive this. My motivation is model fit. This wind direction variable really isn't contributing anything to the model as a continuous variable but before casting it aside, I thought transforming it into a categorical variable might show something useful. The 8 basic map directions seem natural In this same data set I had a variable "days since start" and it was continuous and not significant but when factored in as day of the week, I'm seeing significance on every day.
