Description

Create a dispersal kernel

Usage

dispersal_kernel(
  formula,
  coefs,
  habitat = NULL,
  other.vars = NULL,
  start,
  max.dist,
  init.dir = amt::as_rad(45),
  standardize = TRUE,
  raster = TRUE,
  stop = 0
)

Arguments

formula

[formula] The formula for the dispersal kernel.

coefs

[named numeric]{>1} Coefficients for the terms in the formula. Names of the coefficients must match the name of the terms.

habitat

[RasterLayer] The habitat matrix / landscape.

other.vars

[data.frame = NULL] Possible other covariates.

start

[numeric(2)] Coordinates of the start position.

max.dist

[numeric(1)] The maximum distance of the dispersal kernel.

init.dir

[numeric(1)] The initial direction in rad.

standardize

[logical(1) = TRUE] Should the result be standardized.

raster

[logical(1) = TRUE] Should a RasterLayer be returned.

stop

[integer(1)=1]{0,1} What happens when the animal steps out of the landscape.
