RootTree
Details and Options
- RootTree[Tree[data,{subtree1,subtree2,…}]] returns Tree[data,{}].
- RootTree[Tree[data,None]] gives Tree[data,None].
- RootTree[tree,n] removes all subtrees on levels below level n.
- In RootTree[tree,n], the level n can be any machine integer or Infinity.
- A positive level n+1 consists of all subtrees of tree that are children of subtrees on level n.
- Level 0 corresponds to the root of the tree.
- Level -1 corresponds to the leaves.
- A negative level -(n+1) consists of all subtrees whose children are on levels -1, -2, …, -n, with highest level -n.
- RootTree has the same options as Tree.

RootTree[tree] gives Tree[TreeData[tree],None] when TreeChildren[tree] gives None:
TreeChildren[[image]]RootTree[[image]]% === Tree[TreeData[[image]], None]RootTree[tree] gives Tree[TreeData[tree],{}] when TreeChildren[tree] gives a list:
TreeChildren[[image]]RootTree[[image]]% === Tree[TreeData[[image]], {}]RootTree[tree] gives Tree[TreeData[tree],<>] when TreeChildren[tree] gives an association:
TreeChildren[[image]]RootTree[[image]]% === Tree[TreeData[[image]], <||>]RootTree[tree,-1] gives the whole tree:
