In vpourfaraj/lobsterCatch: Models capture processes in American lobster fishery

This function controls the movements of lobsters toward the trap. There are both directional and random move components considered in this function. The proximity of a lobster to a trap controls the magnitude of each components, i.e closer a lobster gets to the trap the smaller the random component of movement. The directional move depends on radius of influence of a trap and current zone of influence.

Description

This function controls the movements of lobsters toward the trap. There are both directional and random move components considered in this function. The proximity of a lobster to a trap controls the magnitude of each components, i.e closer a lobster gets to the trap the smaller the random component of movement. The directional move depends on radius of influence of a trap and current zone of influence.

Usage

directionalMove(
  Lobster,
  dStep,
  minDistoTrap,
  Trap,
  radiusOfInfluence,
  currentZoI
)

Arguments

Lobster	location of lobster in the grid in x and y coordinates.
dStep	defines the distance that each lobster moves in each time step.
minDistoTrap	defines the minimum distance to the trap.
Trap	location of trap in the grid in x and y coordinates.
radiusOfInfluence	trap's radius of influence.
currentZoI	initial zone of influence

Value

Returns the new coordinates of each lobster in the grid after a directional move is applied.
