This software has evolved from fisheries research conducted at the
Pacific Biological Station (PBS) in 'Nanaimo', British Columbia, Canada. It
extends the R language 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.
Additionally, we include 'C++' code developed by Angus Johnson for the
'Clipper' library, data for a global shoreline, and other data sets in the
public domain. Under the user's R library directory '.libPaths()',
specifically in './PBSmapping/doc', a complete user's guide is offered and
should be consulted to use package functions effectively.

towTracks function

Data frame consisting of 4 columns: <code>PID</code> = primary polygon ID,
 <code>POS</code> = position of each vertex within a given polyline, <code>X</code>
 = longitude coordinate, and <code>Y</code> = latitude
 coordinate. Attributes: <code>projection = "LL"</code>, <code>zone = 9</code>.
