Hi,
I have a dataset which has more than two clusters (say 3 clusters).
I used kmeans to cluster the dataset.
I am wondering how I can plot the clustering result on a two-dimensional
figure????
The example in the kmeans help file is as follows:
x <- rbind(matrix(rnorm(100, sd = 0.3), ncol = 2),
matrix(rnorm(100, mean = 1, sd = 0.3), ncol = 2))
cl <- kmeans(x, 2, 20)
plot(x, col = cl$cluster)
It seems that this is only working for 2 clusters. When my dataset has more
than two clusters, the plot results are obvious wrong.
Any suggestions to plot more than two clusters.
Thanks!!!
