Twitter Data Analysis - Error in Term Document Matrix

Question

Trying to do some analysis of twitter data. Downloaded the tweets and created a corpus from the text of the tweets using the below

# Creating a Corpus
wim_co         


        

Answer 1

I think this problem happens because of some weird characters appear in the text. Here is my solution:

wim_corpus = tm_map(wim_corpus, str_replace_all,"[^[:alnum:]]", " ")


tdm = TermDocumentMatrix(wim_corpus, 
                       control = list(removePunctuation = TRUE, 
                                      stopwords =  TRUE, 
                                      removeNumbers = TRUE, tolower = TRUE))
