[R-sig-Geo] [R] adding text to spplot

[Matevž Pavlič]

Hi,
still have troubles,  if I have a code like this :

spplot(enaD2, "var1.pred",sp.layout=pts,  main = "globina 60 cm", sub="D2", col.regions=terrain.colors(64), contour=T)

i get a nice plot with contours but without text.

If ia use your code :

spplot(enaD2, "var1.pred",sp.layout=pts,  main = "globina 60 cm", sub="D2", col.regions=terrain.colors(64), contour=T, panel = function(x,y,z,...) { sp.points(ena, pch=20, cex=1.5, col="red")
sp.text(coordinates(ena), ena$ime) }    )

I get eeverything else but the actual spplot (just points and labels and a key on the right).

any ideas?

You may need panel function

spplot(enaD2, "var1.pred",sp.layout=pts, main = "globina 60 cm", sub="D2", col.regions=terrain.colors(64), contour=T, panel = function(x,y,z,subscripts,...) {
panel.polygonsplot(x,y,z,subscripts,...)
sp.text(coordinates(enaD2), enaD2$ime[subscripts]) }
