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").

List all available datasets:

ds <- qa_datasets()
head(ds)
