can spplot add features ?
Hi, You could also have a look at the R wiki, there is a part on spatial data visualization using sp-classes: http://wiki.r-project.org/rwiki/doku.php?id=tips:spatial-data:spatial_data_visualization cheers, Paul

Dear listers,
I would like to add the border of a country (SpatialPolygons object
called ChinaBorder) in a spplot built as following:
mypal<-colorRampPalette(c("white", "cyan",
"blue","green","yellow","red"))
statSpat<-SpatialPointsDataFrame(chinagrid,data.frame(n=z))
gridded(statSpat)<-TRUE
spplot(statSpat,col.regions=mypal)
I cannot managed to overlap ChinaBorder to statSpat with the 'panel'
argument of spplot.
Any idea about how to proceed ?
Patrick
