Please include at least an indication of which functions you are using.
The following for SpatialLines objects does work:
SLDF <- contourLines2SLDF(contourLines(volcano))
and this works for SpatialPolygons:
grd <- GridTopology(c(1,1), c(1,1), c(10,10))
polys <- as.SpatialPolygons.GridTopology(grd)
both for base graphics. Are you using spplot()?
