Extract information from string with dots as separator in R

Question

I apologize for possible similar questions, but I just can't find the solution for my problem. So, I have a string with three parts, separated by “.”, for example:

a <- "XXX.YY.ZZZ"

(the length of strings differ, it could also be a <- "XXXX.Y.ZZ", but the three parts are always separated by the two “.”. I solved the problem for the first part:

library(stringi)
stri_extract(a, regex='[^.]*')
[1] "XXX"

Appreciate your help.

I think what you want is `stringi::stri_extract_all(a, regex='[^.]*')`? — tyluRp, Feb 20 '18 at 12:44
You were on the right track. Like @tyluRp said above, you just need to add the `_all` bit to the end of `str_extract`. The regex command I used was a bit different to extract only the characters: `stringi::stri_extract_all(a, regex = "\\w+")` — Logan Connolly, Feb 20 '18 at 12:53
