arc {alphahull} | R Documentation |
This function adds the arc of B(c,r)
between the angles that A_\theta v
and A_{-\theta} v
form with the axis OX, where A_\theta v
represents the clockwise rotation of angle \theta
of the vector v
.

# Plot of the circumference of radius 1
theta <- seq(0, 2*pi, length = 100)
r <- 1
plot(r*cos(theta), r*sin(theta), type = "l")
# Add in red the arc between pi/4 and 3*pi/4
arc(c(0,0), 1, c(0,1), pi/4, col = 2, lwd = 2)
