R: Select points inside a polygon

inpip {splancs} | R 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.
