This tutorial brought together a diverse set of computational biologists and modelers who wanted to expand their expertise and learn how to harness big data and computation using the R language.
A wide range of HPC/Cluster/Cloud computing resources exist and are accessible to researchers, such as Amazon EC2, NSF XSEDE, local clusters, and simple multiprocessor shared memory machines. Participants learned about the strengths and weaknesses of the various platforms and how to enable R to utilize them. The strengths and limitations of R for big data and big computation were also discussed. Moving beyond these basics, further sessions provided participants with hands on experience in the following areas:
In addition to the fundamentals, the tutorial gave attendees a perspective on how these tools can be put to use in biological research. Tutorial examples included applications such as Bayesian mixed models in genomics, phylogenetic biogeography, approximate Bayesian computation, and multivariate data reduction in ecological models. Finally, a special session on teaching with R provided insights on how to bring computational science research into the undergraduate classroom.
This hands-on tutorial gave participants an opportunity to begin applying these tools to their own problems. Presentations and sample codes were available for all tutorial sessions. Attendees also consulted with presenters and platform experts to identify the right tools for their problems.
Participants should have a solid working knowledge of the R language. Experience with a lower level programming language (C, C++, Fortran) will also be beneficial but is not required.

A goal of NIMBioS is to enhance the cadre of researchers capable of interdisciplinary efforts across mathematics and biology. As part of this goal, NIMBioS is committed to promoting diversity in all its activities. Diversity is considered in all its aspects, social and scientific, including gender, ethnicity, scientific field, career stage, geography and type of home institution. Questions regarding diversity issues should be directed to Dr. Ernest Brothers, the NIMBioS Associate Director for Diversity Enhancement (email@example.com).
