Dear all, I am working on a neighbourhood matrix of the postal code areas in the Netherlands. Reading the shapefile and producing the matrix is no problem (after some help from Roger), but I am not completely confident that all neighbours are recognized because there are a few polygon boundaries that are topologically unclean. I have checked the shapefile as closely as possible, but with 4000 postal code areas this is a hell of a job. Plotting the matrix in R (using plot.nb) is also not an option because with so many areas the individual connections are no longer visible. Thus, I would like to zoom in on parts of the graph to check whether all neighbours are defined correctly. I searched the web for methods to zoom in and out of a graph in R, but couldn't find anything. Does anyone know if there are ways to do this?
