[R-sig-Geo] Combining SpatialLines into SpatialPolygons

[Roger Bivand]

Please use plain text only, and provide a small reproducible example, 
possibly demonstrating in code and data what you claim about "finding 
solutions". I assume that you have already tried rgeos::gPolygonize(). 
Consider using its example to generate your reproducible example. You may 
find that scaling also matters.
