Description

Create n turtles at the center of the world with their headings evenly distributed.

Usage

createOTurtles(n, world, breed, color)
# S4 method for numeric
createOTurtles(n, world, breed, color)

Arguments

n

Integer.

world

WorldMatrix or worldArray object.

breed

Character. Vector of breed names. Must be of length 1 or of length n. If missing, breed = "turtle" for all turtles.

color

Character. Vector of color names. Must be of length n. If missing, colors are assigned using the function rainbow(n).

Value

AgentMatrix object of length n with data for the turtles being: xcor, ycor, who, heading, prevX, prevY, breed, and color.

Details

The identity of the turtles is defined by their who number. This numbering starts at 0 and increments by 1.

The coordinates from the previous time step are stored in prevX and prevY. The initial values are NA.
