RulesTree

RulesTree[data{rule1,rule2,…}]

gives a tree whose root contains data and that has children specified by the rulei.

Details and Options

  • RulesTree gives a Tree object.
  • The children of RulesTree[data{rule1,rule2,…}] are given by the list {RulesTree[rule1],RulesTree[rule2],…}.
  • The children of RulesTree[data<|key1rule1,key2rule2,…|>] are given by the association <|key1RulesTree[rule1],key2RulesTree[rules2],…|>.
  • RulesTree[data] for data not of the form …{…}, …<|…|> or …None is equivalent to RulesTree[dataNone]. »
  • RulesTree takes the same options as Tree.

RulesTree can be computed with NestTree:

Possible Issues  (1)

RulesTree[exprNone] is generally equivalent to RulesTree[expr]:

However, the None is necessary to specify a tree with data of the form lhs{e1,e2,…} or lhsNone:

Without the None, this would be treated as a tree whose root contains lhs with children {RulesTree[e1],RulesTree[e2],…}:
