For data of a world map of administrative boundaries, I can also recommend the "Global Administrative Unit Layers" from the FAO Geonetwork catalog http://www.fao.org/geonetwork/ Just enter "GAUL" in the search window. The data exist from 1990 to 2008.
Thanks. These are very good data sets, and show how much work has been put into their construction and delivery. A simpler alternative is shown on an unfinished webpage on my site: http://spatial.nhh.no/R/etc/world_map_intro.html and an older and two newer downloads of worldmaps, the newer ones generalised and much smaller in file size: http://spatial.nhh.no/R/etc/world_countries.rda http://spatial.nhh.no/R/etc/TM_WORLD_BORDERS_SIMPL-0.2.RData http://spatial.nhh.no/R/etc/TM_WORLD_BORDERS_SIMPL-0.2_Mollweide.RData with the latter in the Mollweide projection. They use the classes defined in the sp package. The work was "done" in connection with a QUEST workshop in Devon UK in early July. They are all RData files to load directly into R. Hope this helps, Roger

Hi all, Sorry if this is a dumb question.... I'm trying to produce a world map showing WinBUGS useage from the data collected at the mrc-bsu web-site. I've been trying to use the map + mapdata packages but was surprised to find that the geography of the world map seemed a little out-of-date, being specified in terms of USSR and Yugoslavia, for instance. I wondered if there was a more up-to-date version available somewhere?? Best wishes + many thanks for any help you can give... Dave Lunn
