this is a normal R error - to compute homeranges, subsets of points 
determined by the attribute in the colum you chose (for esample animal 
ID, month, year...) must contain at least 5 points. Even one subset with 
<5 points raises this error.
I suggest to group points by another column.
On my side, I will change the code to avoid Python error, and raise a 
info window instead.

many thanks and best regards,

Anne
