## Generate a grid of points

### Description

Generate a grid of points

### Usage

    gridpts(poly,npts,xs,ys)

### Arguments

`poly` | polygon in which to generate the points
`npts` | approximate number of points to generate
`xs,ys` | grid spacing in x and y Either `npts` or `xs` and `ys` must be specified. If all three are given then `xs` and `ys` are ignored.

### Value

A points object containing a grid of points inside the polygon. If `npts` is specified, then a grid spacing `xs` and `ys` will be calculated to give approximately `npts` in the polygon. If `xs` and `ys` are given then these will be used to generate a number of points in the polygon.
