Define a `habitat' grid for kernel smoothing

Source: R/kud_tools.R

This function defines a `habitat' grid for kernel smoothing (e.g., via kud_around_coastline).

kud_habitat(map, mask = map, mask_inside = FALSE, plot = TRUE, ...)

Arguments

map

A raster that defines grid properties.

mask, mask_inside

Mask options passed to mask_io.

plot, ...

A logical input that defines whether or not to plot the habitat grid, alongside any additional arguments passed to plot.SpatialPixelsDataFrame.

Value

The function returns a SpatialPixelsDataFrame object that defines `habitat' (1) versus `non-habitat' (0).
