From splancs v2.01-40
by Roger Bivand

Select points inside a polygon

- Keywords
- spatial

##### 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.
