Create a coordinate reference string (CRS), suitable for use as a projection argument to mapPlot() or plot,coastline-method().




character string indicating the region. This must be in the following list (or a string that matches to just one entry, with pmatch()): "North Atlantic", "South Atlantic", "Atlantic", "North Pacific", "South Pacific", "Pacific", "Arctic", and "Antarctic".


string contain a CRS, which can be used as projection in mapPlot().


This is a preliminary version of this function, with the results being very likely to change through the autumn of 2016, guided by real-world usage.
