Removing duplicate words in a string in R
duplicates, r
Solution
If you are still interested in alternate solutions you can use `unique` which slightly simplifies your code.
paste(unique(d), collapse = ' ')
As per the comment by Thomas, you probably do want to remove punctuation. R's `gsub` has some nice internal patterns you can use instead of strict regex. Of course you can always specify specific instances if you want to do some more refined regex.
d <- gsub("[[:punct:]]", "", d)
Problem
Just to help someone who's just voluntarily removed their question, following a request for code he tried and other comments. Let's assume they tried something like this: ``` str <- "How do I best try and try and try and find a way to to improve this code?" d <- unlist(strsplit(str, split=" ")) paste(d[-which(duplicated(d))], collapse = ' ') ``` and wanted to learn a better way. So what is the best way to remove a duplicate word from the string?
