prune_table: Recursively prune a TableTree

Description

Recursively prune a TableTree

Usage

prune_table(
  tt,
  prune_func = prune_empty_level,
  stop_depth = NA_real_,
  depth = 0,
  ...
)

Value

A TableTree pruned via recursive application of prune_func.

Arguments

tt

(TableTree or related class)
a TableTree object representing a populated table.

prune_func

(function)
a function to be called on each subtree which returns TRUE if the entire subtree should be removed.

stop_depth

(numeric(1))
the depth after which subtrees should not be checked for pruning. Defaults to NA which indicates pruning should happen at all levels.

depth

(numeric(1))
used internally, not intended to be set by the end user.

...

named arguments to optionally be passed down to prune_func if it accepts them (or ...)
