[R-sig-Geo] spplot and labels

[Patrick Giraudoux]

Hi again,

I am working with spplot and would like to draw labels on a number if 
items. I supposed that one must use the layout arguments of spplot, but 
I understand from the doc that  sp.text(loc, txt, ...) can be used only 
for one location and not for a matrix of locations (as the 'classical' 
text function does in the package base).

Is there a way to pass a matrix of locations + labels to the layout 
argument ?

Thanks in advance,

Patrick
