Dear All,
I am using raster to do my  geographic plots. I also use maps package to
generate world map in geographic coordinates.

However, I am interested in organizing my data in magnetic coordinates. I
have converted my data points from geographic coordinates to magnetic
coordinates.

My problem now is to generate world map in magnetic coordinates.
Can anybody please give me a hint on how to go about this.

Thanks for your time


Regards
Ogbos
