Dear R-helpers I have two SpatialPolygonsDataFrame objects, but I want to plot only the boundary between them. The boundary object is to be overlaid I plot that I have made, so I would strongly prefer a method that does not rely on grid graphics.
Thank you in advance for any pointers. Kind regards, Peter. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
