Dear List,

I have examined the sp, maptools, and shapefiles packages (Windows) but cannot seem to figure out a solution for writing shapefiles for 'curvy shapes'. The scenario is that I generate a series of polygons, circles, and ellipses on a plot and would like to convert them to shapefiles. Since the circles and ellipses are do not return a coordinate list during the plotting sequence (e.g., all I need supply are the lengths of axes and rotation angle), is there an easy way by which the plot window can be converted to a shapefile?

Thank you,

Tarmo
