thinlines equivalent?
maybe you can try the function dp() in the package "shapefiles", which is an implementation of the Douglas-Peucker polyLine simplification algorithm. Hope it helps David David Hugh-Jones a ?crit :
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).
