How to create a cluster plot in R?

Question

How can I create a cluster plot in R without using clustplot?

I am trying to get to grips with some clustering (using R) and visualisation (using HTML5 Canvas).

Answer 1

Here you can find one graph to analyze cluster results, "coordinate plot", within "clusplot" package.

It is not based on PCA. It uses function scale to have all the variables means in a range of 0 to 1, so you can compare which cluster holds the max/min average for each variable.

install.packages("devtools") ## To be able to download packages from github
library(devtools)
install_github("pablo14/clusplus")
library(clusplus)

## Create k-means model with 3 clusters
fit_mtcars=kmeans(mtcars,3)

## Call the function
plot_clus_coord(fit_mtcars, mtcars)

This post explains how to use it.
