define_shapefiles

An internal function to make <code>basemap</code> code more readable

internal

Allows plotting data on bathymetric maps using 'ggplot2'. Plotting
oceanographic spatial data is made as simple as feasible, but also flexible
for custom modifications. Data that contain geographic information from
anywhere around the globe can be plotted on maps generated by the basemap()
or qmap() functions using 'ggplot2' layers separated by the '+' operator. The
package uses spatial shapefiles stored in the 'ggOceanMapsData' package,
geospatial packages for R to manipulate, and the 'ggspatial' package to help
to plot these shapefiles. High-resolution shapefiles for detailed maps are
stored on GitHub and downloaded automatically when needed.
