Unfortunately, your code is not self-contained.
Please provide a completely self-contained set of commands which illustrate
the problem (as described in the posting guide).
If you mean a problem that the boundaries don't quite line up, as illustrated
by:
map("france")
map("world", col=2, add=T)
then try using the "worldHires" database from the mapdata package.
