Examples
N = 25
x = rnorm(N)
y = rnorm(N)
z = rnorm(N)
######## draw pentagons
plot(x,y, type='n', axes=FALSE, ann=FALSE)
pgon(x,y, siz=abs(z)/10, col="white", border='black', startalph =60, K=5, lwd=.5, xpd=TRUE)
###### color the points, use 4-sided blocks
rbow=rainbow(100)
ss = sample(1:100, N, replace = TRUE, prob = NULL)
plot(x,y, type='n', axes=FALSE, ann=FALSE)
pgon(x,y, siz=abs(z)/10, col=rbow[ss], border='black', startalph =60, K=4, lwd=.5, xpd=TRUE)
