My best suggestion is you read up on OPeNDAP, and how ti works as a service.
OPeNDAP can have as the basis of its service any number file formats. What it
does when it sends the request over the internet is transform each of these
internal representations into a common external representation, which is an
OpeNDAP binary.
The latest versions of the netcdf library take it one step further, by making
the remote files appear as netcdf files, and to be accessible by netcdf api
commands. But even in this case, while the netcdf library hides the details,
what gets transported is an OpeNDAP binary.
I would repeat my suggestion that you more closely read posting guides, in
particular what r-help sends you to, in particulat
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html and
http://www.catb.org/~esr/faqs/smart-questions.html. If you gave a small,
complete program that can reproduce the problem that you are finding, than
people have something specific that they can comment on. The error you are
reporting could be from so many issues, because it is unclear what steps you
have taken.
Regards,
-Roy
