How do I clean twitter data in R?

Question

I extracted tweets from twitter using the twitteR package and saved them into a text file.

I have carried out the following on the corpus

xx<-tm         


        

Answer 1

To remove the URLs you could try the following:

removeURL <- function(x) gsub("http[[:alnum:]]*", "", x)
xx <- tm_map(xx, removeURL)

Possibly you could define similar functions to further transform the text.
