Get information on whether a node is a leaf (meaning that it doesn't have any children) and whether it is named.

Usage

node_is_leaf(x)

node_is_named(x)

node_is_named_leaf(x)

Arguments

x

A node, either from tree_root() or from another node_*() function.

Value

A logical value.

Examples

src <- "x <- rnorm(100, mean = 2)
    any(duplicated(y))
    x <- z + 1
    any(duplicated(x))"

root <- src |>
  tree_new() |>
  tree_root()

node_is_leaf(root)
#> [[1]]
#> [1] FALSE
#> 

root |>
  node_find(ast_rule(pattern = "z")) |>
  node_is_leaf()
#> $rule_1
#> [1] TRUE
#>
