[R-sig-Geo] index of eccentricity

[David March Morlà]

Dear list,

I would like to calculate an index of eccentricity (ECC) of an animal's 
home range (a polygon determined with adehabitat package and then 
exported as shapefile). ECC=l/w, where 'l' is the maximum lenght of the 
polygon, and 'w' is the maximum width of the polygon. Could you 
suggestme any package that implements this function or that could help 
me to compute 'l' and 'w'?
Thank you,
