The wordcloud package is word clouds for R with a difference: they look great.
Of course, having just analysed online coverage of the ISMB conference, I had to run all 6 906 comments from the 2008-2011 meetings through some code. If you followed along via the Sweave code, I went as far as generating the data frame of comments, ismb.comments, then pulled the comment text into a new data frame using:
It was then simply a case of following along with the excellent example code from the post Word Cloud in R, over at One R Tip A Day, limiting myself to the 1000 most-used words. Watch out, the TermDocumentMatrix() function from the tm package uses quite a lot of memory.
