Uses ggplot2 syntax and shape files to plot research data on oceanographic maps anywhere around the globe.
The general map-making function for ggOceanMaps is
basemap. This function creates a "canvas" on which research data
can be plotted. The basemap function is analogous
to ggplot function from the ggplot2 package.
Remember to use data = <<NAMEOFDATASET>> for additional geometries
you plot on basemaps (basemap(60) + geom_point(data =
data.frame(lon = 50, tat = 70), aes(x = lon, y = lat)) as an example).
