Good question. The R script below illustrates how to find the area of
overlap between isopleths for two individuals. This is relatively easy
because T-LoCoH saves isopleths (and hulls) as SpatialPolygonDataFrames,
which is a pretty common format for spatial objects in R so there are a
lot of packages and functions that can manipulate polygons in this format.
Check that out and let me know if you have any other questions.
