Researchers in Dr. Karen Abbott’s lab recently released a software package for studying stochastic dynamical systems. The package, written for the programming language R, is called QPot (short for quasi-potential, which is one of its primary analytic tools). Postdoctoral research associates Christopher Moore, Christopher Stieha, and Ben Nolting, collaborated with Maria Cameron (University of Maryland) to create QPot, which they hope will be useful to researchers in a wide variety of scientific disciplines, ranging from ecology to physics. QPot is now available on the Comprehensive R Archive Network (CRAN) at http://CRAN.R-project.org/package=QPot.  Members of the lab have also written two related papers, one developing the use of the quasi-potential in ecology (accepted for publication in the journal Ecology) and one demonstrating applications of the QPot package itself (submitted to The R Journal).
