a couple of ideas/proposals
....
I'm starting to think that the right abstraction for hdf5 is as
arrays (not dataframes) since the slabs are homogeneous. For us they
are just ints or floats but they can be arbitrary so maybe the
abstraction really is dataframe.
In any event, the interesting question is about arraySubscript.
(and I guess other similar functionality).
Currently this gets (int dim, SEXP s, SEXP x)
where s is the subscript argument and x is the object itself. All
we do with x is to ask it for its dim attribute and potentially its
DimNames attribute.
We would like to use arraySubscript...

o Option 'repositories' to list URLs for package repositories
added.
o package.description() has been replaced by packageDescription().
o R CMD INSTALL/build now skip Subversion's .svn directories as

o arraySubscript and vectorSubscript take a new argument which
is a function pointer that provides access to character
strings (such as the names vector) rather than assuming these
are passed in.
