data |
A forest. |
name |
'NULL' (default) or a scalar character specifying the node name of child nodes. |
A forest.
Climb a forest from parents to children with one or more node names.
climb(.data, ..., .recurse = TRUE, .deep)climb(.data, ..., .recurse = TRUE, .deep)
.data |
A forest. |
... |
A list of node names to climb the forest. |

.f |
A function, formula, or vector (not necessarily atomic). |

Additional arguments passed on to the mapped function. |
.climb |
Climbing or descending? |
A forest.
Apply a function hierarchically to a forest in the climbing or descending direction.
