A tokenIndex with the rows of the nodes in the selected branches removed

Examples

spacy_conjunctions <- function(tokens) {
  no_fill = c('compound*','case', 'relcl')
  tq = tquery(label='target', NOT(relation = 'conj'),
              rsyntax::fill(NOT(relation = no_fill), max_window = c(Inf,0)),
              children(relation = 'conj', label='origin',
                       rsyntax::fill(NOT(relation = no_fill), max_window=c(0,Inf))))
  tokens = climb_tree(tokens, tq)
  chop(tokens, relation = 'cc')
}

## spacy tokens for "Bob and John ate bread and drank wine"
tokens = tokens_spacy[tokens_spacy$doc_id == 'text5',]

tokens = spacy_conjunctions(tokens)
