[R-sig-Geo] spplot : varying dots for multiple parameters

[Torleif Markussen Lunde]

In that case I would produce:

pdf("filename.pdf")
print(spplot(Insitu_sp, "SPM", parameters as suggested earlier))
dev.off()

pdf("filename.pdf")
print(spplot(Insitu_sp, "Si", etc))
dev.off()

and edit (move legends etc) in Incscape or some other post editing software. 
That would be the fastest way to do this (and not trying to get a different 
legend for each plot). One of the good things about lattice is that it makes 
graphs comparable.

Best wishes
Torleif
