Brownian bridge motion

Description

This function simulates a brownian bridge motion

Usage

simm.bb(date = 1:100, begin = c(0, 0), end = begin, id = "A1",
        burst = id, proj4string=CRS())

Arguments

date

a vector indicating the date (in seconds) at which relocations should be simulated. This vector can be of class POSIXct

begin

a vector of length 2 giving the x and y coordinates of the location beginning of the trajectory

end

a vector of length 2 giving the x and y coordinates of the location ending the trajectory

id

a character string indicating the identity of the simulated animal (see help(ltraj))

burst

a character string indicating the identity of the simulated animal (see help(ltraj))

proj4string

a valid CRS object containing the projection information (see ?CRS from the package sp).

Value

An object of class ltraj.
