When it comes to presuading people to embrace R I have found that a discussion of the benefits of open source software is very effective. My institution trains a large number of graduate students from developing countries who will likely have limited access to research funds when they return. Pointing out the benefits of training on an open access platform to the future research careers of these students has gotten many onside. The same arguement applies to students who will be working for small companies that cannot afford/justify a SAS license.

First, such questions should be addressed to r-help. Second, "PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code." Concerning the random samples, I would suggest Quick-R [1] for a good beginner's guide to R, and for bootstrapping techniques [2].
