Lovely ppt from the formidable Jeffrey Bean, whose lucid style in explaining R has made me a big fan of his awesome work!
Take at look at his extensive collection of Big Data with R slides at http://jeffreybreen.wordpress.com/2012/03/10/big-data-step-by-step-slides/ – they are both very comprehensive and a delightful addition to anyone wishing to go the cloud, hadoop, R route
His blog at http://jeffreybreen.wordpress.com/ talks of lots of very relevant topics.
