[R-sig-Geo] spatial clusters

[Dorina Lazar]

Georg,

Thanks for being very patient with me. 
 
I have not a shapefile for countries.

I have tried to obtain it. I have loaded a shapefile for Finland, GIS data, from  http://www.eea.europa.eu/data-and-maps/data/eea-reference-grids/zipped-shape-file-finland

and I tried to read the file FI_1K.shp
Fin<- readShapePoly(system.file("etc/shapes/ FI_1K.shp", package="spdep"))
but...
Error in getinfo.shape(filen) : Error opening SHP file

How can I obtain, for each country,  the shapefile spatial polygon in R (SpatialPolygons-DataFrame)?

Thanks again,
Dorina
