I see functions to rasterize in the raster package but nothing to vectorize...

and certainly nothing to do buffer around polygons.

raster package will do all those things. See the vignette for specifics.

Hi list,

I trying to find how to do two operations in R:

1-Convert (vectorize) a raster to polygons

2-Make buffers around a set of polygons

Thanks for your help,

Pierre
