Description
The function polylist2list() extracts the vertices of the polygons from a polylist object, seperating polygons from each other by 3 rows of NaN.
Usage
1
Arguments
data
A polylist object
Details
The user can then represent the coordinates of sites of a polylist object
as background map, using the option carte included in all interactive functions of GeoXp.
Value
It returns a matrix of numeric values with 2 columns (x and y coordinates
of the vertices of the polygons) where polygons are seperated from each other by 3 rows of NaN.
