Hello, I am trying to build a regex to extract vowels and consonants from a string. So far, I am able to extract the basic a-e-i-o-u sequence using the following extension to the String class: class String def vowels scan(/[aeiou]/i) end def consonants scan(/[^aeiou]/i) end end examples: >> "Mary had a little lamb".vowels => aaaiea >> "Mary had a little lamb".consonants => mryhdlttllmb However, the regex does not accommodate the conditional treatment of ''y'...

Hi Iago, This is not a bug. It is expected. Patterns may not overlap. However, there is a way to get the result you want using perl: ```R gsub("([aeiouAEIOU])(?=[aeiouAEIOU])", "\\1_", "aerioue", perl = TRUE) ``` The specific change I made is called a positive lookahead, you can read more about it here: https://www.regular-expressions.info/lookaround.html It's a way to check for a piece of text without consuming it...

...PERL type matching. The idea: separate the two vowels in the regex by a character that you know cannot appear (if there is such) and match it optionally, e.g. with '*" repetition specifier. I used "?" for the optional character below (which must be escaped). > gsub("([aeiouAEIOU])\\?*([aeiouAEIOU])", "\\1_\\2", "aerioue") [1] "a_eri_ou_e" Cheers, Bert On Fri, Mar 1, 2024 at 3:59?AM Iago Gin?

Hi all, I tested next command: gsub("([aeiouAEIOU])([aeiouAEIOU])", "\\1_\\2", "aerioue") with the following output: [1] "a_eri_ou_e" So, there are two consecutive vowels where an underscore is not added. May it be a bug? Is it expected (bug or not)? Is there any chance to get what I want (an underscore...

Hi, I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with single column which contain the 30,000 students names. There were typo errors while entering this student names.
