S3 class for rasterized fitted density surfaces. A Dsurface is a type of `mask' with covariate(s) for the predicted density at each point.
# S3 method for Dsurface
print(x, scale = 1, ...)
# S3 method for Dsurface
summary(object, scale = 1, ...)
Dsurface object to display
numeric multiplier for density
other arguments passed to print method for data frames or summary method for masks
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.
