Existing R Packages for use in climate analysis

The CRAN web site has a wide range of contributed packages for statistical analysis. Below is a list of CRAN contributed packages useful for climate analysis. These are the installation instructions for the Unix platform and the Windows system.

R packages for reading and writing NetCDF files

  • RNetCDF: R interface to NetCDF datasets. Author: Pavel Michna. Important note: The NetCDF and the udunits libraries must be already installed on your unix system so that you can install this package.
  • ncvar: High level R interface to NetCDF datasets. Author: Juerg Schmidli.

R packages for plotting maps

  • maps: Draw Geographical Maps. Author: Ray Brownrigg and Thomas P Minka
  • mapdata: Extra Map Databases. Author: Ray Brownrigg.
  • mapproj: Map Projections. Authors: Ray Brownrigg and Thomas P Minka.

The web page of Peter Dunn from the University of South Queensland has useful information on how to obtain coast line datasets for plotting maps.
