MikkoVihtakari/ggOceanMaps: Second CRAN release of the package

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()
function 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.

Contains the functionality of the CRAN version 1.1
