adding text to spplot

Hi,

help(spplot):

     The ?sp.layout? argument is either a single layout item, or a list
     with a layout items. A layout item is a list with its first
     argument the name of the layout function to be called: ?sp.points?
     for SpatialPoints, ?sp.polygons? for SpatialPolygons object,
     ?sp.lines? for a SpatialLines object, and ?sp.text? for text to
     place. The second argument contains the object (or text) to be
     plotted; remaining arguments are passed to the corresponding
     ?panel.*? functions.

And first example of help(spplot):

     data(meuse)
     coordinates(meuse) <- ~x+y
     l2 = list("SpatialPolygonsRescale", layout.north.arrow(), offset =
     c(181300,329800), scale = 400)
     l3 = list("SpatialPolygonsRescale", layout.scale.bar(), offset =
     c(180500,329800), scale = 500, fill=c("transparent","black"))
     l4 = list("sp.text", c(180500,329900), "0")
     l5 = list("sp.text", c(181000,329900), "500 m")
     
     spplot(meuse, c("ffreq"), sp.layout=list(l2,l3,l4,l5),
     col.regions= "black", pch=c(1,2,3),
     key.space=list(x=0.1,y=.95,corner=c(0,1)))

Bye, 

Oscar.

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?
