Suggestion: Dimension-sensitive attributes
Starting by working on an interface
In the case the metadata are stored in a list, that interface enforces the
building of a list.
(I said to ignore implementation for now, but paradoxically this made me
consider possible implementations).
Creating the list on the fly if it's not stored internally as a list should be
cheap.

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
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
Hi,
maybe this has been suggested before, but would it be possible,
without not breaking too much existing code, to add other dimension
vector attributes in addition to 'dimnames'? These attributes would
then be subsetted just like dimnames.
Something like this:
x - array(1:30, dim=c(2,3,5))
12 matches
