Density Surfaces

Description

S3 class for rasterized fitted density surfaces. A Dsurface is a type of ‘mask’ with covariate(s) for the predicted density at each point.

Usage

## S3 method for class 'Dsurface'
print(x, scale = 1, ...)
## S3 method for class 'Dsurface'
summary(object, scale = 1, ...)

Arguments

x, object

Dsurface object to display

scale

numeric multiplier for density

...

other arguments passed to print method for data frames or summary method for masks

Details

A Dsurface will usually have been constructed with predictDsurface.

The ‘scale’ argument may be used to change the units of density from the default (animals / hectare) to animals / km^2 (scale = 100) or animals / 100km^2 (scale = 10000).

A virtual S4 class ‘Dsurface’ is defined to allow the definition of a method for the generic function raster from the raster package.
