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/quantarcticR")Example
library(quantarcticR)quantarcticR will download data from whichever Quantarctica mirror has been selected. The USA mirror is chosen by default, but you can change this: see help("qa_mirror").
