quantarcticR

Quantarctica is a collection of Antarctic geographical datasets which works with the free, cross-platform, open-source software QGIS. It includes community-contributed, peer-reviewed data from ten different scientific themes and a professionally-designed basemap.

The quantarcticR package provides access to Quantarctica data sets for R users, without needing QGIS to be installed. R users can use these data sets with e.g. the raster, sp, or sf packages.

Installation

You can install the development version of quantarcticR from GitHub with:

remotes::install_github("SCAR-sandpit/quantarcticR")

This is very much a work in progress!
