Hi, Colleagues.

As shown at the bottom, I was able to obtain information from a column (named "Message") of a text data (named "SMSSpamCollection" (i.e., SMSSpamCollection$Message[44]).  But when I ran
SMSSpamCollection.token <-tokens(SMSSpamCollection$Message, what="word",
+                                  remove_url = TRUE,
+                                  remove_numbers= TRUE, remove_punct= TRUE,
+                                  remove_symbols= TRUE, remove_hyphens= TRUE)
The feedback was
Error in tokens.default(SMSSpamCollection$Message, what = "word", remove_url = TRUE,  :
  tokens() only works on character, corpus, tokens objects.

I would appreciate some guidance to fix the error message!

Thank you.
