arc {alphahull} | R Documentation |
This function adds the arc of B(c,r) between the angles that A_θ v and A_{-θ} v form with the axis OX, where A_θ v represents the clockwise rotation of angle θ of the vector v.
arc(c, r, v, theta, ...)
c |
Center c of the arc. |
r |
Radius r of the arc. |
v |
Vector v in the plane. |
theta |
Angle θ (in radians). |
