[R] Calculate individual R2n values

Does anyone know an alternate way of calculating R2n with spatial data other
than converting values into ltraj format (adehabitat package)?  

I have a series of geographic xy coordinates (in metres).  I imagine I can
subtract x1y1 from x2y2 to get the spatial difference (dxdy), but what
function can I use to calculate R2n (i.e. net squared displacement) using
this information?
