Library "tm" Error Corpus.Default()

Hi guys,

Please, Im trying to build a corpus and a wordcloud. My data comes from a csv with 36000 answers (qualitative). Could you please help me to understand the following error:

install.packages("tm")

Try

mycorpus <- VCorpus(x = VectorSource( Data_bag) ),
                     readerControl = list(reader=readPlain,
                                          language="en"))

Thank you, does not work...

"Error: ',' unexpected in "mycorpus <- VCorpus (x = VectorSource (Data_bag)),""

Ok. I had a typo, as I'm on mobile the 2nd bracket close after databag should be delete. Because the brackets need to pair up, right?
Sorry about the confusion.

[felipe.vaz]

WOW, works niceeeee dudeee....thx

[felipe.vaz]

but, to understand, could you please tell me what it does?

Turned your vector of character/text into a Volatile Corpus.
It's a bit dry but the documentation is here:
