Howdy Gurus I 'd like to ask a question about how to build TermDocMatrix in tm text mining package. It is not clear about importing a plain text file, and them converting that text file into TermDocMatrix file, etc to me. How can I build a TermDocMatrix of " a plain text document file for text association? Or are there any good manuals? Thank you in advance, --...

Below is a section of the code that I have used and an excerpt of the output: What I wanted to be able to do is to view the output alphabetically - rather than the results being sorted by frequency as below, that an alphabet...
