Layout turtles on a circle — layoutCircle • NetLogoR

Relocate the turtles on a circle centered on the world.

layoutCircle(world, turtles, radius, torus = FALSE)

# S4 method for worldNLR,agentMatrix,numeric
layoutCircle(world, turtles, radius, torus = FALSE)

Arguments

world: WorldMatrix or worldArray object.
turtles: AgentMatrix object representing the moving agents.
radius: Numeric. Radius of the circle.
torus: Logical to determine if the world is wrapped. Default is torus = FALSE.

Value

AgentMatrix representing the turtles with updated coordinates and updated data for their heading values and previous coordinates prevX

and prevY.

Details

The turtles point outwards.

     If the

     `radius` value leads `turtles` outside of the `world`'s extent

     and `torus = TRUE`, they are

     relocated on the other sides of the `world`, inside its extent; if

     `torus = FALSE`, the `turtles` are located past

     the `world`'s extent.

Examples

w1 <- createWorld(
  minPxcor = 0, maxPxcor = 9, minPycor = 0, maxPycor = 9,
  data = runif(100)
)
t1 <- createTurtles(n = 10, coords = randomXYcor(w1, n = 10))
plot(w1)
points(t1, col = "black", pch = 16)

t1 <- layoutCircle(world = w1, turtles = t1, radius = 3)
points(t1, col = "red", pch = 16)
