Description

Union one or more JamPolygon objects

Usage

union_JamPolygon(jp, new_name = NULL, verbose = FALSE, ...)

Arguments

jp	JamPolygon
new_name	character string to define optional names(jp) of the output. Otherwise it uses the first name in jp.
verbose	logical indicating whether to print verbose output.
...	additional arguments are ignored.

Value

JamPolygon after applying the union
