I used deldir to generate voronoi but it seems that I can only specify rectangular window for the rw option. Is there a way the system can take in non-rectangular polygon as study area?
No, only rectangular windows are permitted. You could try a large window, and then code using templates in maptools to use the gpclib intersect function to cookie-cut the external polygons. At least deldir does permit polygon closure within the rectangle. Roger
