Hello all,

I don't have a question about a specific function, so much as I'm wondering
if a specific type of function exists in R.
I have multiple continuous-variable rasters (elevation, temperature,
precipitation) and I would like to obtain some kind of measure of
environmental heterogeneity based on these variables across a landscape
(that would be defined by a bounding polygon). I know such methods exist
for categorical variables (for example in the SDMTools package with the
PatchStat function), but I can't seem to find anything that would work with
continuous data.

Any suggestions or advice would be greatly appreciated. Thanks for your
time!

-Pascal
