[R-sig-Geo] Accurate spatial database for country administrative boundaries

[Manuel Spínola]

Dear list members,

I am looking for a global accurate spatial database for countries'
administrative boundaries.

I tried the raster package, using the getData function and the GADM
database and rgeoboundaries for the geoboundaries database, but I get
differences between them.

Is there any other spatial database for administrative boundaries
accessible from R, so I can compare and decide which one is the most
accurate of the open access spatial database for the countries I am
interested?

Thank you very much in advance.

Manuel
