This is a simple two-element vector containing x,y coordinates for a source or central location associated with a spatial point pattern. In this example, the center location represents a point of importance in an individuals daily activity pattern. Surrounding point locations are places physically contacted by an individual during a particular time interval. Demonstration data mimics UTM coordinates such that the first element represents Easting (x), and the second, Northing (y).
The format is a two-element vector of numeric entries.
The coordinates of the center must have the same units and projection as the remaining point observations.
This demonstration data has been manufactured for illustrative purposes only.
