[R-sig-Geo] Azimuthal equidistant projection and rgdal

[Johan Mazel]

Hi
I am trying to use the solution rpesented here:
https://stat.ethz.ch/pipermail/r-sig-geo/2007-December/002939.html.

However it looks like the shifted (from the north pole) map is
displayed on top on the original azimuthal equidistant projection
centered on the north pole.
Is there any way to correct this ?

Thanks for your time.
Regards.
Johan
