I am using rtweet library as a homework, I don't get any error running the code chunks, but when
I knit the Markdown file, I get this error message:
tweets2<- tweets_3 %>% mutate(text = str_replace_all(text,'(http|https)[^([:blank:]|\"|<|&|#\n\r)]+', "")) %>% select(created_at, text)
Object 'tweets_3' not found
