Rstudio hierarchical clustering
WebMar 24, 2024 · A single-linkage clustering dendrogram was constructed using Ward’s hierarchical clustering method with Euclidean distances to assess co-resistance patterns of isolates and was illustrated in a heatmap using the heatmap.2 package with ggplots and RColorBrewer libraries in R software. Webmclust (Fraley et al.,2016) is a popular R package for model-based clustering, classification, and density estimation based on finite Gaussian mixture modelling. An integrated approach to finite mixture models is provided, with functions that combine model-based hierarchical clustering, EM for mixture estimation and several tools for …
