Regex named groups in R

Question

For all intents and purposes, I am a Python user and use the Pandas library on a daily basis. The named capture groups in regex is extremely useful. So, for example, it is r

Answer 1

Base R does capture the information about the names but it doesn't have a good helper to extract them by name. I write a wrapper to help called regcapturedmatches. You can use it with

myRegex = "(?<textOcc>t[e]?xt)|(?<wordOcc>word)"
m<-regexpr(myRegex, origText, perl=T, ignore.case=T)
regcapturedmatches(origText,m)

Which returns

     textOcc wordOcc
[1,] "text"  ""     
[2,] "TEXT"  ""     
[3,] "TXT"   ""     
[4,] ""      "Word" 
[5,] ""      ""     
[6,] "text"  ""     
[7,] ""      "word"
