An interesting, and topical, example of multivariate data for classroom illustrations are the American college football rankings. Starting at the end of October (or "week 8", the 8th week of the football season) a set of rankings called the BCS (Bowl Championship Series) will be published. This is a composite ranking based on two subjective polls, the Harris and USA Today polls, and a trimmed mean of 6 objective scores, the so-called computer rankings. The Harris and USA Today polls are currently available along with several others (the best known and most often quoted is the AP poll but, for complicated reasons, it was replaced in the BCS rankings by the Harris poll).
I enjoy using these as classroom examples but I haven't found a web site from which I can download the data directly and am reduced to "screen scraping" the HTML from popular sites like ESPN. Does anyone know of a site from which one can download the current poll results? ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
