[R-sig-Geo] sp 1.0-0 package: sp.polygons in levelplot behaviour

[Jonathan]

Hello all, 

I updated my version of sp to 1.0-0 today and am getting a different
behaviour when using levelplot and sp.polygons.  The polygons do not appear
to be terminating when I run the following code.  Anyone else have this
problem?  It does seem to work if I use spplot though.  I have previous code
that uses lattice::levelplot and rasterVis::levelplot which I can modify to
spplot but would rather not have to.

library(sp)
library(maptools)
library(lattice)
library(raster)
library(rasterVis)

nc <- readShapePoly(system.file("shapes/sids.shp", package="maptools")[1],
proj4string=CRS("+proj=longlat +datum=NAD27"))
r <- raster(nc)
r[] <- 1
levelplot(r,
              panel = function(x,y,z,col.regions,subscripts,region,...){
                 panel.levelplot.raster(x, y, z, subscripts=subscripts)
                 sp.polygons(nc)
               }
)


Thank you,
Jonathan
