Creating the list on the fly if it's not stored internally as a list should be

different classes.
Disabling "dim<-" is, I think, choosing sanity for now.

Same for me (about your comments).

It would also help to ensure a smooth transition from the existing

with 3 elements, something like:

Would something like this make sense for R-core
--either for standard arrays or as a new class--
or would it be better implemented in a package?

There have been times when I've thought this could be useful too.
One way to go about it could be to introduce a special attribute that
controls how attributes are dealt with in subsetting, e.g.,
"attr.dimname.like". The contents of this would be character data; on
subsetting, any attribute t
Hi,
I agree with Henrik that his suggestion to have "dimension vector attributes"
working like dimnames (see below) would be an extremely useful infrastructure
adittion to R.
If this is not considered for R-core, I am happy to try to implement this in a
package, as a new class. And possibly do
