Webhclust_avg <- hclust (dist_mat, method = 'average') plot (hclust_avg) Notice how the dendrogram is built and every data point finally merges into a single cluster with the height (distance) shown on the y-axis. Next, you can cut the dendrogram in order to create the desired number of clusters. WebIn order to create a dendrogram in R first you will need to calculate the distance matrix of your data with dist, then compute the hierarchical clustering of the distance matrix with hclust and plot the dendrogram. Option 1. Plot the hierarchical clustering object with the plot function. # Distance matrix d <- dist(df) # Hierarchical clustering ...
