How to do it...

Perform the following steps to draw a bivariate cluster plot:

1. Install and load the cluster package:

        > install.packages("cluster")
        > library(cluster)  

2. You can then draw a bivariate cluster plot:

        > clusplot(customer, fit$cluster, color=TRUE, shade=TRUE)  

The bivariate clustering plot of the customer dataset

3. You can also zoom into the bivariate cluster plot:

        > par(mfrow= c(1,2))
        > clusplot(customer, fit$cluster, color=TRUE, shade=TRUE)
        > rect(-0.7,-1.7, 2.2,-1.2, border = "orange", lwd=2)
        > clusplot(customer, fit$cluster, color = TRUE, xlim = c(-0.7,2.2),        ylim = c(-1.7,-1.2))  

The zoom-in of the bivariate clustering ...
