[R-sig-eco] Fwd: spatial analysis with dbMEM

[THIOULOUSE JEAN]

Hi

You need to load the adegraphics package AFTER loading the ade4 and adespatial packages.

There are two versions of the s.label function : one in the ade4 package and one in the adegraphics package. The one you need here is the second one.
