Report the amount by which the
turtles' coordinates ycor would change
to move forward the given distances with their current headings.
dy(turtles, dist = 1) # S4 method for agentMatrix,numeric dy(turtles, dist = 1) # S4 method for agentMatrix,missing dy(turtles)
AgentMatrix object representing the moving agents.
Numeric. Vector of distances the
Numeric. Vector of length
Report the cosine of the
turtles' heading multiplied by the
values. Heading 0 is north and angles are calculated in degrees in a
