readGDAL will only work if you the rgdal package against an underlying
GDAL library that includes JPEG2000. The Windows binary on CRAN does
not.
In R rgdal is the only route I know of, but the steps to compile are
not trivial - it is probably easier in this sense on Linux, but I'd
say you better look outside of R for a conversion.
rgdal and JPEG2000 is usually discussed on R-Sig-Geo mailing list
since they are primarily used for spatial data.
If you are on Windows (you don't say) there is a way to access
JPEG2000 with OSGeo4W, but that is a topic for a different mailing
list.
Cheers, Mike.
