R Question

Sentiment analysis using R

Are there any R packages that focus on sentiment analysis? I have a small survey where users can write a comment about their experience of using a web-tool. I ask for a numerical ranking, and there is the option of including a comment.

I am wondering what the best way of assessing the positiveness or negativeness of the comment is. I would like to be able to compare it to the numerical ranking that the user provides, using R.

And there is this package:

sentiment: Tools for Sentiment Analysis

sentiment is an R package with tools for sentiment analysis including bayesian classifiers for positivity/negativity and emotion classification.

Update 14 Dec 2012: it has been removed to the archive...

Update 15 Mar 2013: the qdap package has a polarity function, based on Jeffery Breen's work
