How to remove spplot() polygon fill in R

Question

When I 'spplot' a SHP polygon imported with readOGR, the darned thing is always color filled. The color bar shows that it is using the shapefile ID value, with a single value.

Is there a way to get rid of the ID value and fill?

Thanks!

Like @JoshO'Brien said:

spplot(SpDF, fill = NA, colorkey = FALSE)

Does what you need.
