[R-sig-Geo] Kriging

[Edzer Pebesma]

You may have (near) duplicate points in your data.

Other packages let you control more when you want to kriging, see the
Spatial task view on CRAN.

To me, kriging::kriging seems a bit of a black box: does it compute
Euclidian distances from long/lat coordinates directly? How does it fit
variogram models?
