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
