[R-sig-Geo] thinlines equivalent?

[David Hugh-Jones]

Hi all

I have a big dataset of points and am doing stuff on them that takes a
lot of time. To speed it up, I would like to use "thinlines" from
RArcinfo, which basically makes the maps "rougher" by throwing away
points. Is there an equivalent function for SpatialPolygon type
objects? (I assume that there's no way to convert _to_ Arcinfo, though
I know it's possible to read from it).

Cheers
