Our research stems from experiences with information on Canada s Pacific groundfish fisheries compiled at the Pacific Biological Station (PBS). Despite its origins in fishery data analysis, our software has broad applicability. The library PBS Mapping extends the languages R and S-PLUS to include two dimensional plotting features similar to those commonly available in a Geographic Information System (GIS). Embedded C code speeds algorithms from computational geometry, such as finding polygons that contain specified point events or converting between longitude-latitude and Universal Transverse Mercator (UTM) coordinates. We also present a number of convenient utilities for the Microsoft Windows operating systems, including commands that support computational geometry outside the framework of R or S-PLUS. Tools to construct most of our software come freely from the Internet, as documented here in a guide to the packages available. Furthermore, we provide quick tutorials that address key technical issues relevant to our work, such as embedding C code into an R package and writing documentation that meets the R standard. Our results, which depend significantly on the work of students, illustrate the convergence of goals between academic training and applied research.1.61 MBPDFenAll Rights Reservedsoftware developmentfisheriesReport
