n turtles at the center of the
world with their headings evenly
createOTurtles(n, world, breed, color) # S4 method for numeric createOTurtles(n, world, breed, color)
WorldMatrix or worldArray object.
Character. Vector of "breed" names. Must be of length 1 or of length
Character. Vector of color names. Must be of length
AgentMatrix object of length
n with data for the
turtles being: "xcor", "ycor", "who", "heading", "prevX", "prevY", "breed",
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
