Hello,

Thank you. Now I have another problem, when I run the code you've 
provided error messages occur.

 > library(maptools)
 > bordures<-readShapeSpatial("10m_cultural/ne_10m_admin_0_countries.shp")
Error in getinfo.shape(fn) : Error opening SHP file
 >
 > library(rgdal)
 > readOGR(dsn="10m_cultural", layer="ne_10m_admin_0_countries")->bordures
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, 
use_iconv = use_iconv,  :
   Cannot open file


How can I solve this?
