Hi everyone,
I want to plot some pattern. For example, I have some coding as below,

plot(0:11,type="n")
polygon(c(6,8,10), c(7,3,5),bor=6)
polygon(c(2,4,6), c(5,3,7),bor=6)
polygon(c(6,10,8), c(7,9,11),bor=6)
polygon(c(2,6,4), c(9,7,11),bor=6)

This coding will give me four triangles, but how to generate more triangles
in sequences so
that not need to mention the coordinate for each triangle?

Thank you.
