Matrix (ncol = 2) with the first column "xcor" and the second
column "ycor" representing the turtles inital locations.
WorldMatrix or worldArray object.
Numeric. Vector of values between 0 and 360. Must be of length 1 or
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", and "color".
coords is provided,
world must not be provided.
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
