r-cran-maps Documentation


GNU R support for producing geographic mapsThis package provides facilities for easily producing maps based on data sets in the GNU R statistical computing environment. . The r-cran-maps package includes map data for the United States (including state and county-level maps), New Zealand, and a world map; additional maps (including a higher-resolution world map) are available in the suggested r-cran-mapdata package. . The suggested, non-free r-cran-mapproj package adds facilities for calculating geographic projections, which are used by mapmakers to compensate for the inaccuracies inherent in projecting a spheroid's surface onto a two-dimensional plane.
