R help - Apr 2010 - Maps: Country coding

Hello,

I am using the maps library for plotting maps.

To build new geograhical sets such as Europe I use

europe = c('Germany','Netherlands',...)

Is there a list of county codes used by the map function.

Thanks,
Berthold

If you mean the names of the countries, have a look at the file:
${R_HOME}/library/maps/mapdata/world.N which lists the name associated with
every polygon.

Note that the maps database is historical, for example Czechoslovakia is one
country.

Hope this helps,
