Hi All,



I have a Data.frame that looks like that one below. I would like to do some text
mining on it to possibly find some patterns between Opis, ACklasifikacija and
Vodja. I looked over a tm package which loks promissing, more specifically
DocumentTermMatrix or TermDocumentMatrix. But I can not figure out how to change
my data from data.frame to Corpus or VCorpus.
