Setting the traits of the levels — lvl

Use this function to create a "vector" of levels. The vector is actually comprised of a data frame with a column labels and other columns with corresponding level attribute (if any). This data frame can be accessed with lvl_data().

Usage

lvl_attrs(
  levels = NULL,
  labels = NULL,
  prefix = "",
  suffix = "",
  sep = edibble_labels_opt("sep"),
  include_leading_zero = edibble_labels_opt("leading_zero"),
  data = NULL,
  ...
)

Arguments

levels: A vector that either denotes the index number or short name of the levels.
labels: An optional character vector that is the long name format of levels.
prefix: The prefix of the labels.
suffix: The suffix of the labels.
sep: A string to add between prefix and levels.
include_leading_zero: A logical value to indicate whether there should be a leading zero added to level indexes. This is ignored if levels is not numeric.
data: A list or data frame of the same size as the levels.
...: Name-value pair denoting other level attributes. The value should be the same length as levels or a single value.

Value

An edbl_lvls object.
