[R-sig-Geo] polygons to arcs?

[Tim Keitt]

Is there an 'sp' function that takes a polygon as its argument and
returns a set of line objects corresponding to the arcs in the
polygon?

Or better yet, a function that given a set of polygons, returns the
hull? (ie the set of singleton arcs after applying the polys to arcs
function)
