Convert SpatialPolygon objects into MAPshp objects

Description

as.MAPshp converts a SpatialPolygon or SpatialPolygonsDataframe object downloaded using getShp into a 'MAPshp object (data.frame) for easy plotting with ggplot.

Usage

as.MAPshp(object)

Arguments

object

SpatialPolygon or SpatialPolygonsDataframe object to convert into a 'MAPshp'.

Value
