inpip: Select points inside a polygon

inpipR Documentation

Select points inside a polygon

Description

Select points inside a polygon

Usage

inpip(pts,poly,bound=NULL,quiet=TRUE)

Arguments

pts

A points data set

poly

A polygon data set

bound

If points fall exactly on polygon boundaries, the default NULL gives arbitrary assignments. If TRUE, then all points "on" boundaries are set as within the polygon, if FALSE, outside.

quiet

Do not report which points are on boundary for non-NULL bound

Value

inpip returns a vector of indices of the points in pts that are located in the polygon. Note that "in" is an arbitrary concept for points "on" the polygon boundary.
