(This article was first published on

**Zero Intelligence Agents » R**, and kindly contributed to R-bloggers)I have just uploaded a bunch of new videos the Rchive (yea, that’s what I am calling it now).

Most of the videos are from the April NYC meetup, which include the following talks:

- Pankaj Chopra—using R and Bioconductor (http://www.bioconductor.org/) for biomarker detection in cancer
- Andrew Ilardi—an R project that analyzes a list of stocks while reaching out to the web to pull their historical prices, then plots Quarter over Quarter correlations and a year over year scatter plot
- Andrew Little—often in game theory we are interested in the behavior of equations with no explicit solution. In this talk, Andrew Little demonstrates how to use the optim() and other functions in R for such situations
- Jared Lander—the science, and statistics, of finding the best pizza slience in New York City

As an added bonus, I came across the original full lenfth video of Andrew Little’s talk on Zelig and Matching in R from the August 2009 meetup, so I added it the Rchive (said it again)—enjoy!
