R package for conducting stock assessment simulation studies using Stock Synthesis 3.  The code is being developed for a 'FISH600 project' by students at the School of Aquatic and Fishery Sciences, University of Washington. The project will develop assessment models, operating models, and associated R functions for stock assessment simulation studies using Stock Synthesis. The project aims to complete several studies, the results of which will be presented at the World Conference on Stock Assessment Methods in Boston, July 2013.
