qdapRegex 0.1.3 BUG FIXES pastex would throw a warning on a vector (e.g., pastex(letters)). This has been fixed. youtube_id was documented under qdap_usa rather than qdap_supplement and contained an invalid hyperlink. This has been fixed. rm_citation contained a bug that would not operate on citations with a comma in multiple authors before the and/& sign. See issue #4 NEW FEATURES is.regex added as a logical check of a regular expression's validy (conforms to R's regular expression rules). rm_postal_code added for removing/extracting/replacing U.S. postal codes. Case wrapper functions, TC (title case), U (upper case), and L (lower case) added for convenient case manipulation. group function added to allow for convenient wrapping of grouping parenthesis around regular expressions. rm_citation_tex added to remove/extract/replace bibkey citations from a .tex (LaTeX) file. regex_cheat data set and cheat function added to act as a quick reference for common regex task operations such a lookaheads. rm_caps_phrase added to supplement rm_caps, extending the search to phases. explain added to view a visual representation of a regular expression using http://www.regexper.com and http://rick.measham.id.au/paste/explain. Also takes named regular expressions from the regex_usa or other supplied dictionary. MINOR FEATURES last_occurrence regex added to the regex_supplement dictionary to find the last occurrence of delimiter. word_boundary, word_boundary_left, and word_boundary_right added to regex_supplement dictionary to provide a true word boundary. Regexes adapted from: http://www.rexegg.com/regex-boundaries.html#real-word-boundary rm_time2 regex added to the regex_usa dictionary to find time + AM/PM IMPROVEMENTS The regex_usa dictionary regular expressions: rm_hash, rm_tag, rm_tag2 and rm_between pick up grouping that allows for replacement of individual sections of the substring. See ?rm_hash and ?rm_tag for examples. pastex picks up a sep argument to allow the user to choose what string is used to separate the collapsed expressions. rm_citation, rm_citation2, and rm_citation3 now attempt to include last names that contain the lower case particles: von, van, de, da, and du.
