Dependency heatmap

In the following dependency heatmap, rows are the parent packages of quantmod and columns are the dependency packages that each parent package brings in. On the right side of the heatmap, there are three barplot annotations: 1. number of imported functions/S4 methods/S4 classes from parent packages; 2. number of dependency packages from each parent package; 3. heaviness of each parent package on quantmod.
