How to see polygons vertex

Hi,

I want to see all the vertex of a SpatialPolygonsDataFrame in a plot. Should I convert or extract the coordinates of each polygons and then plot them? How?

Thanks,

Pierre
Ok got it:
plot(imagev01 at polygons[[1]]@Polygons[[1]]@coords)
Now when I plot the polygon itself (there is only one):
plot(imagev01)
it is much less large than the set of point and they don't matches... The heights fit though.

Am I doing something wrong?

Pierre
