The problem is that tsdiag is a generic (the same in both packages),
and package TSA sets methods for it (and methods for classes in
package stats which has already registered methods).
ought to work (it does for me in your example), but please take with
up with the maintainer of package TSA.
(I would be inclined to copy out of package TSA the parts your want
and not load the rest.)
