But how would I do so without hard coding the name er12.l?
I set up a reproducible example. In the following my regression fo...

Two similar zoo objects with different structures, how to get same structure?
..., "origin")= Named num [1:3] 1 1 1970
.. .. ..- attr(*, "names")= chr [1:3] "month" "day" "year"
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:12] "ED4 COMDTY" "ED12 COMDTY" "ER4 COMDTY" "ER12 COMDTY" ...
I also have a vector of dates of same length as zoo object (5219):
> str(bldates)
chr [1:5219] "01/01/90" "01/02/90" "01/03/90" "01/04/90" "01/05/90"
