Thank you, Renaud, and Bill Dunlap.
There is obviously a bit of a problem there, but it may well be
"only" a problem in error handling.
As Bill's trace(get, ..) shows, R tries to get
"#HAS_DUPLICATE_CLASS_NAMES" which is indeed an indication of the problem:
You are trying to *RE*define a class union that already exists
*identically* in the Matrix package:
In the R-forge development version of 'Matrix', it is
line 717 of Matrix/R/AllClass.R (and that will be close also
in the CRAN version of Matrix).
So at least for you, Renaud, the solution to the problem is easy:
Just don't do what you should not do: What you want is already
part of Matrix.... and after searching: It's been part of
Matrix since ca. July 2012 ...
--
But yes, there's a buglet in the 'methods' package currently,
which leads to a misleading error message
(It's arguable if it *should* give an error which it did not previously;
I think it would be quite a good idea to give at least a
warning as you are masking class definition of the Matrix
package which is in your search() path or at least among the
loaded namespaces at this time).
Best,
Martin
