R Documentation

Extract nouns from row and column labels

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

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

`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`.

A list of nouns from row and column labels.

get_nouns("a [b]", notation = bracket_notation)
# Also works with vectors and lists.
get_nouns(c("a [b]", "c [d]"))
get_nouns(list("a [b]", "c [d]"))
