Dear Robert, 
I was replying to the thread because I have also encountered the same issue
that Gerardo mentions but believe that your recommendation does not address
the issue.
I have been using the mahal classifier function (Dismo package in r) in
several of my analyses and recently I have discovered that it seems to give
apparently wrong distance results for points that are identical to points
used in training of the classifier. I have recently posted a question on
stack overflow without realizing that this thread existed. In it I document
the odd behavior in multiple ways. 


BTW, thanks very much for the work on the Dismo package. It is truly an
amazing tool set.

Best regards,
