To remove double spaces and dates from strings, we can use the following regular expression: gsub("\\b(?:End(?:\\s+DATE|(?:ing)?)|(?:0?[1-9]|1[012])(?:[-/.](?:0?[1-9]|[12][0-9]|3[01]))?[-/.](?:19|20)?\\d\\d)\\b|([\\s»]){2,}", "\\1", x, perl=TRUE, ignore.case=TRUE) Here’s a breakdown of how it works: \\b matches the boundary between a word character and something that is not a word character. (?:End(?:\\s+DATE|(?:ing)?)|...) groups two alternatives: The first one, End, captures only if followed by " DATE" or " ing". The second one matches the date pattern \d{2} (two digits).
