title: Generate regularly spaced points in polygon
body: <p>Is there a way to generate regularly spaced (e.g., 500 meters apart) points within a polygon using R? I have been trying to use the sp package but can't seem to define a set of points that are spaced a certain distance apart from one another. My aim is to generate the points, then extract their lat/long coordinates into a new dataframe. Any help would be much appreciated! Thanks</p>
