It puzzles me why you have not investigated an error message that seems quite
informative. When I looked at the code of timeSeries::interpNA I was puzzled
that the package seems to use "timeSeries" as the class name. This
error reports a different class name, but it does seem that the function is
designed to take only a particular set of intputs and yours fails that test.

So the lack of an error here suggests that a ts-object might be acceptable to
the same function that you were asking about.
