[R] french map

[Christophe Declercq]

Nathalie,

You could have a look at the web site of the Institut Géographique National
(http://www.ign.fr) where you can download a free SHAPEFILE with polygon
data for the French départements. You can choose one of two projections:
LAMBERT II étendu or LAMBERT 93
(http://www.ign.fr/affiche_rubrique.asp?rbr_id=810&lng_id=FR). In the
associated DBF file, you get the name and the x,y coordinates for the
préfecture of each département.

You could use these data in R with one of the packages which read shapefiles
(for example, 'shapefiles' which is on CRAN or the draft package 'maptools'-
see http://spatial.nhh.no/R/ - which is already very useful as it is).

I hope it helps.

Christophe
