Web25 de set. de 2024 · The function HCPC () [in FactoMineR package] can be used to compute hierarchical clustering on principal components. A simplified format is: HCPC(res, nb.clust = 0, min = 3, max = NULL, graph = TRUE) res: Either the result of a factor analysis or a data frame. nb.clust: an integer specifying the number of clusters. WebThe working of the AHC algorithm can be explained using the below steps: Step-1: Create each data point as a single cluster. Let's say there are N data points, so the number of clusters will also be N. Step-2: Take two closest data points or clusters and merge them to form one cluster. So, there will now be N-1 clusters.
