Hi Mark and anyone else who is listening I have just fixed the map plots. Apologies that this has taken sooooooo long. The changes have just been pushed to the development version and have been checked on my windows machine. Note that you were correct also about there being an issue with using plmapfill. It turned out that the type specified in the shapefile was overriding the render type specified by the user.
While I was there I realised there was a problem with rendering polygons that wrap round the whole globe such as Antarctica so that should now be fixed too. For those who may now how plfill works a bit better than me, something that is supported by shapefiles, but currently not by plmap, is holes. A polygon in a shapefile consists of multiple parts and clockwise parts are filled whereas anticlockwise parts are holes. Is this something we can do relatively easily with plfill or is it not really doable?
