Creates an object of class RootDepSet with two empty slots $value and $root.
The slots are supposed to be assigned values. The simplest way is using method setRootDepSet.
Every node with observable variable should be taken as a root.
A subset of nodes is created for every root.
For every root a subset of nodes must be created.
For other examples see Vignette "Subsets and Coordinates".
