R help - Aug 2009 - R Package That Contains International Geomagnetic Reference Field (IGRF)

By any chance is anyone aware of an R package that contains a representation of
the International Geomagnetic Reference Field (IGRF)?
http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html

I've tracked down some Fortran and C code for the IGRF-10, and possibly
IGRF-11, and was hoping to avoid an awkward port.

Thanks again for any feedback and leads provided.

I guess I will broaden the question to include any Earth Geomagnetic Model, e.g.
DoD World Magnetic Model (WMM).  Does there exist an R package that includes any
geomagnetic model?

Here is an example of a couple of others provided by NASA, e.g.
http://www.ngdc.noaa.gov/geomag/models.shtml

Unless I hear back, I guess I will investigate porting these to R as a function
and then as a package.

Thanks again for the insights and feedback.
