[R-sig-Geo] Add shape over a ppp density plot

[Angelo Moreno]

Hi, I have  created a ppp with coordinates(longitude/lattitude),I have
obtained the density plot:

plot(density.ppp(ppbog07, 0.0003))

then I need, and I would like to see the shape map over this plot...I have
tried with this:

plot(shape,add=T)

but it doesn`t work. What problem could exist or maybe exist another way?

Thanks!
