⚠️There's a newer version (2.2.0) of this package.Take me there.

ggOceanMaps (version 1.1)

Plot Data on Oceanographic Maps using 'ggplot2'

Description

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.
