Results from the Standard Deviation Box Calculator (calc_box) are stored in a list object. This object is required for the plot function (plot_box).

1 |

The list object contains the following results:

- id
Identifier for the SD box

- points
a simple two-column data frame (or matrix) containing x,y coordinates for a series of point locations.

- calcentre
Boolean: Indicates whether the mean centre was computed

- weighted
Boolean: TRUE if the weighted mean centre is to be used instead

- weights
Weights applied to point observations

- CENTRE.x
Actual, used x-coordinate of centre

- CENTRE.y
Actual, used y-coordinate of centre

- SDD
Standard deviation distance value

- SDx
Orthogonal standard deviation in x-direction

- SDy
Orthogonal standard deviation in y-direction

- Box.area
Area of orthogonal standard deviation box

- NW.coord
Coordinates of the north-west extent of the SD Box

- NE.coord
Coordinates of the north-east extent of the SD Box

- SW.coord
Coordinates of the south-west extent of the SD Box

- SE.coord
Coordinates of the south-east extent of the SD Box

The coordinates of the points must have the same units and projection as the specified center.

This demonstration data has been manufactured for illustrative purposes only.
