[R] track on boats

A good choice might be to store your data in objects of class

Then you can assign any attributes you want to each line, such as your
vessel, type, destination, or status.

This will make it relatively easy to, for example, plot subsets of tracks
specified by different attributes.

SpatialLinesDataFrame objects are defined in the sp package.

For further help, I would suggest the r-sig-geo mailing list. Also look at
the CRAN Task View "Spatial".
