Error in regular expressions- Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)

[Sharang Bhat]

I am building a sentiment miner for Twitter. The program was working fine before I upgraded R to R 3.2.2. The error is as follows

Error in stri_replace_all_regex(string, pattern, replacement, vectorize_all = vec,  : 
  Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)
Error in stri_replace_all_regex(string, pattern, replacement, vectorize_all = vec,  : 
  Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)
Error in stri_replace_all_regex(string, pattern, replacement, vectorize_all = vec,  : 
  Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX)

The code associated with the error is this (I'm assuming)

tweets <- str_replace_all(tweets," "," ")
    # Get rid of URLs
    tweets <- str_replace_all(tweets, "http://t.co/[a-z,A-Z,0-9]*{8}","")
    # Take out retweet header, there is only one
    tweets <- str_replace(tweets,"RT @[a-z,A-Z]*: ","")
    # Get rid of hashtags
    tweets <- str_replace_all(tweets,"#[a-z,A-Z]*","")
    # Get rid of references to other screennames

Hi Sharang,

This is more of an R question than a shinyapps.io question.  I would either post it to stackOverflow, or you could consider filing a bug for the issue with a reproducible example here: https://github.com/hadley/stringr

Best,

Tareef
