There's been a bit of interest in my code so I'll try and make an R
package out of it very soon.
Also I've discovered some slight modification can make
authentic-looking river networks - I've added a bit to my blog post to

Depends on your GIS! Shapefiles only have a 1-1 relationship, but
that's because they are a bit rubbish. If you use a proper spatial
database then you can do one-many. This is an application for a
PostGIS or Spatialite database, and if your GIS can read that (Qgis
for example) then you are

1. Delete polygons that doesn't have a match with record in joined /
merge table of the shapefile.
(Done transpose and merging - joined to one-to-one relationship already.)
2. Create a subset of

I realised that deleting the polygon with does match wit the record is
not possible since, I can read the shapefile at all. But still I need
