How to display cluster graph with R?

I am using k-means clustering using R and I divide the data set with two clusters

clus.data <- df[,1:14]
head(clus.data)
heart.cluster <- kmeans(clus.data,2)

how to plot the graph with cluster to view them?

Solution

  • One thing I should point out is that you should scale your data set before k-means as a form of standardisation of the data (if you haven't scaled it already that is!):-

    clus.data <- df[,1:14]
head(clus.data)
scaledData<-scale(clus.data)
heart.cluster <- kmeans(scaledData,2)

    You could use the factoextra package.

    library(factoextra) # clustering algorithms & visualization

    And to visualise:

    fviz_cluster(heart.cluster, data = scaledData)
