How to remove punctuation inside brackets in R
I have tried to split documents into sentences, but there are some strange outcomes due to punctuation inside brackets. So I'd like to remove any punctuation.
example input:
A <- c('How to remove all punctuations(like this?) in side it?')
wanted output:
"How to remove all punctuations(like this) in side it?"
r brackets punctuation

Note it's generally considered that there is no need to add the language title into questions. Also, there's no need to comment to thank people for a solution--but you should use the check mark to accept the answer (gives them points, and resolves the question).

Perhaps something like this using a positive lookahead?
gsub("[?!;,.](?=\))", "", A, perl = T)
#[1] "How to remove all punctuations(like this) in side it?"
Or using POSIX character classes
gsub("[[:punct:]](?=\))", "", A, perl = T)
Or if you need to match other types of closing brackets (e.g. curly, square)
gsub("[[:punct:]](?=[)\]}])", "", A, perl = T)
