[R] Help With Graphs

Hi guys,

I am truing to draw a circle and choose 10 points on the circle and put a
number from 1 to 10 above each point. I don't have a problem with drawing a
circle and choosing 10 points. my problem is with numbering . is it even
possible to put a number above each chosen point? if so any idea how to do
it?

ps: the circle has red dots and the selected points are in black.

here is my code:

D=cos(2*pi*(0:9)/10)
C=sin(2*pi*(0:9)/10)

x1=(sin((0:100)*2*pi/100))
y1=(cos((0:100)*2*pi/100))
plot(x1,y1,col="red")

points(C,D)

Thanks,
--
