Set the pbg= argument to set the "bg" (background) to something

that the documentation, which should be in ?"SpatialPolygons-class"
where the plot method is described, is in the maptools package, in ?
plot.polylist - this will be fixed.
Thanks.
plot(pseSP,col='red', pbg='white')
works. But this also implies that:
- one is not able to create a transparent hole(?)
- and one has to care about the correct plotting order or to set the
correct pbg if that 'hole' belongs to another polygon
