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.
