PBSdata contains data objects used primarily by the R packages PBStools for illustrating utility examples and PBSmapx for drawing various coastline and boundary shapefiles. The data herein either exist in the public domain or are non-proprietary and open for public use.
A useful set of data (regional boundaries, key codes, example data), a GUI interface to PBSmapping, and handy utility functions evolved over time (2007-2012) in one R package called PBSfishery. In April 2012, we decided to split this package into three separate libraries -- PBSdata, PBSmapx, and PBStools -- for public distribution (see pbs-software). The three packages experience different levels of change, with PBStools undergoing frequent revision, while PBSdata and PBSmapx remain unchanged for long periods of time.
