Heatmap
A heatmap is a graphical representation of data in which each value is represented by a different colour. It’s very helpful for analysing complicated data sets and spotting trends or correlations between variables. Large datasets may be interpreted and analysed more easily because each cell in the heatmap represents a data point and is coloured according to its value.
Adding a Dendrogram to a ggplot2 Heatmap in R
A potent technique that improves the visualisation of hierarchical clustering patterns inside data is to add a dendrogram to a ggplot2 heatmap in R. Dendrograms shed light on the connections and resemblances among data points, assisting in the discovery of distinct clusters or groups. We will examine how to combine dendrograms with ggplot2 heatmaps using R in this article, enabling a more thorough comprehension of intricate data structures and patterns.
