### HOW DID WE CREATE THIS FILE?
### (This example takes some time and will therefore not be run
###  unless you type: example(worldcountries, run.dontrun=TRUE) )

## Not run: 
# if(require(maps) & require(maptools) & require(raster) & require(rgeos)){
#     worldmap <- map("world", fill=TRUE, plot=FALSE)
#     worldcountries <- map2SpatialPolygons(worldmap, IDs=worldmap$names)
#     worldcountries <- gBuffer(worldcountries, byid=TRUE, width=0)
#     proj4string(worldcountries) <- CRS("+proj=longlat +datum=WGS84")
#     worldcountries
#     ## uncomment the following to store the file:
#     #save(worldcountries, file="worldcountries.rda", compress="xz")
# }
# ## End(Not run)
