Rotate the turtles
's headings to the left of angle
degrees.
left(turtles, angle)
# S4 method for agentMatrix,numeric
left(turtles, angle)
AgentMatrix
object representing the moving agents
.
Numeric. Vector of angles in degrees by which to rotate the turtles
'
headings. Must be of length 1 or of length turtles
.
AgentMatrix
representing the turtles
with updated heading
values.
If a given angle
value is negative, then the turtle
rotates to the right.
