[R-sig-Geo] units of spatial distance in variogram

[Edzer Pebesma]

if your data are latitude/longitude, and you specified them to be so 
(i.e., is.projected(object) is TRUE), then distance is in km, else 
distance is in the units of the original data coordinates.

(I recognized your output to come from gstat::variogram, but please 
mention such details in future postings)
