How to remove punctuation inside brackets in R












0














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

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)
