x <- rbind(cbind(rnorm(400, 0,4), rnorm(400, 0,4)),
cbind(rnorm(400,10,8), rnorm(400,40,6)),
cbind(rnorm(400,30,4), rnorm(400, 0,4)),
cbind(rnorm(400,40,4), rnorm(400,20,2)),
cbind(rnorm(400,50,4), rnorm(400,50,4))
)
clx5 <- clara(x, 5)
## Mis`classification' table:
table(rep(1:5, rep(400,5)), clx5$clust) # -> 1 "error"
summary(clx5)
## Graphically:
par(mfrow = c(3,1), mgp = c(1.5, 0.6, 0), mar = par("mar") - c(0,0,2,0))
plot(x, col = rep(2:6, rep(400,5)))
plot(clx5)
