Extract nouns from row and column labels — get

Nouns are the first part of a row-column label, "a" in "a [b]". Internally, this function calls get_pref_suff(which = "pref").

Usage

get_nouns(
  labels,
  inf_notation = TRUE,
  notation = RCLabels::notations_list,
  choose_most_specific = TRUE
)

Arguments

labels: A list or vector of labels from which nouns are to be extracted.
inf_notation: A boolean that tells whether to infer notation for x. Default is TRUE. See infer_notation() for details.
notation: The notation type to be used when extracting nouns. Default is RCLabels::notations_list, meaning that the notation is inferred using infer_notation().
choose_most_specific: A boolean that tells whether to choose the most specific notation from notation when inferring notation. Default is TRUE.

Value

A list of nouns from row and column labels.
