Rectangular Mask

Share:

Description

Convert a mask or Dsurface with an irregular outline into a mask or Dsurface with a rectangular outline and the same bounding box. This enables contour plotting.

Usage

1
rectangularMask(mask)

Arguments

mask

object of class mask or Dsurface

Details

The covariates of new points are set to missing. The operation may be reversed (nearly) with subset(rectmask, attr(rectmask, "OK")).

The results are unpredictable if the mask has been rotated.

Value

A rectangular mask or Dsurface with the same ‘area’, ‘boundingbox’, ‘meanSD’, ‘polygon’ and ‘polygon.habitat’ attributes as mask. A logical vector attribute ‘OK’ is added identifying the points inherited from mask.
