Keywords
classes
Note

This class is identical to “"gpc.poly"” and is needed because the file formats for polygons without holes is slightly different from the file format for polygons with holes. For a “gpc.poly.nohole” object, the hole flag for each contour is always FALSE.

Also, write.polyfile will write the correct file format, depending on whether the object is of class “gpc.poly” or “gpc.poly.nohole”.

Objects from the Class

Objects can be created by calls of the form ‘new("gpc.poly.nohole", ...) or by calling read.polyfile’.
