rm_endmark(text.var, trim = !extract, clean = TRUE, pattern = "@rm_endmark", replacement = "", extract = FALSE, dictionary = getOption("regex.library"), ...)
TRUE removes leading and trailing white
spaces.TRUE extra white spaces and escaped
character will be removed.fixed = TRUE) to be matched in the given
character vector. Default, @rm_endmark uses the
rm_dollar regex from the regular expression dictionary from
the dictionary argument.pattern.TRUE the endmark strings are extracted into a
list of vectors.pattern begins with "@rm_".gsub.Remove/replace/extract endmarks from a string.
The default regular expression used by rm_endmark finds
endmark punctuation used in the qdap package; this includes ! . ? * AND
|. This behavior can be altered (to ; AND : or to use just ! . AND ?) by
using a secondary regular expression from the
regex_usa data (or other dictionary) via
(pattern = "@rm_endmark2" or pattern = "@rm_endmark3"). See
Examples for example usage.
