Hi Maurizio,

I used the rcorr function from the Hmisc package to calculate the Pearson correlation.

Subject: [R-sig-Geo] Collinearity test

Hallo everybody,
I'm working with Species Distibution Models to predict the potential distribution of a forest specie.
I use WorldClim raster data for Italy and before running SDMs algorithm I would like to test the collineariy between factors to eliminate redundancy of data.
My question in: is there a package that can be used to Test collinearity between factors of a raster stack (worldclim biovariables)?
