computing the convex hull
and project points onto the closest edge (perpendicular distance), that
would give you an ordering but it would be approximate.

I have a set of points that form a polygon, except that they are in
the wrong order. For example, source into R the object "tmpsub" given
below. Then do
plot(tmpsub)
polygon(tmpsub)
You will see that although the points define a polygon, they are in
the wrong order.
I need an algorithm to p
