d  <- dist(iris)
hc <- hclust(d)
svg("iris_silhouette.svg")
c2 <- cutree(hc, k=2)
c3 <- cutree(hc, k=3)
c4 <- cutree(hc, k=4)
si2 <- silhouette(c2, d)
si3 <- silhouette(c3, d)
si4 <- silhouette(c4, d)
par(mfrow=c(2,2))
plot(hc, hang = -1)
plot(si2, col="black")
plot(si3, col="black")
plot(si4, col="black")
