Dependency heatmap

In the following dependency heatmap, rows are the parent packages of pgirmess 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 pgirmess.

imports: number of imported functions/objects; importMethods: number of imported S4 methods; importClasses: number of imported S4 classes.

Required packages: number of strong dependency packages for each of the parent package (or in other words, number of dependency packages the parent package brings in).

Heaviness from parent on pgirmess: number of required packages that can be reduced if moving parent package to Suggests of pgirmess.

The following table lists pairs of parent packages with co-heaviness larger than 10. The co-heaviness measures the number of additional dependencies that two parent packages simultaneously import and are only imported by the two parents.

Note the co-heaviness from parents can be always easily observed in the dependency heatmap.
