  replacement = "",
  extract = FALSE,
  dictionary = getOption("regex.library"),
  ...
)

ex_abbreviation(
  text.var,
  trim = !extract,
  clean = TRUE,
  pattern = "@rm_abbreviation",
  replacement = "",
  extract = TRUE,
  dictionary = getOption("regex.library"),
  ...
)

Arguments

• text.var: The text variable.
• trim: logical. If TRUE removes leading and trailing white spaces.
• clean: trim logical. If TRUE extra white spaces and escaped character will be removed.

• replacement: Replacement for matched pattern.
• extract: logical. If TRUE the abbreviations are extracted into a list of vectors.
• dictionary: A dictionary of canned regular expressions to search within if pattern begins with "@rm_".
