Please include at least an indication of which functions you are using. The following for SpatialLines objects does work: library(sp) SLDF <- contourLines2SLDF(contourLines(volcano)) length(slot(SLDF, "lines")) plot(SLDF, lwd=1:10) and this works for SpatialPolygons: grd <- GridTopology(c(1,1), c(1,1), c(10,10)) polys <- as.SpatialPolygons.GridTopology(grd) plot(polys, lwd=3) both for base graphics. Are you using spplot()?
