rworldmap: A New R package for Mapping Global Data
CONTRIBUTEDRESEARCHARTICLES35rworldmap: A New R package forMapping Global Databy Andy SouthAbstractrworldmapis a relatively new pack-age available on CRAN for the Mapping and vi-sualisation of Global data. The vision is to makethe display of Global data easier, to facilitate un-derstanding and communication. The initial fo-cus is on data referenced by country or grid dueto the frequency of use of such data in Global as-sessments. Tools to link data referenced by coun-try (either name or code) to a map, and then todisplay the map are provided as are functions tomap Global gridded data. Country and griddedfunctions accept the same arguments to specifythe nature of categories and colour and how leg-ends are formatted. This package builds on thefunctionality of existing packages , particularlysp,maptoolsandfields. Example code is pro-vided to produce maps, to link with the pack-agesclassInt,RColorBrewerandncdf, and toplot examples of publicly available country andgridded datasets are becoming increasingly commonand are frequently seen on the web, in journal pa-pers and in our newspapers (for example a carbonatlas of Global emissions available ).
