It seems to only works for zoo or ts objects?
It was tested for zoo, ts, and plain numeric vectors.
I tried to run it for xts objects, and error message occurs.
I had a quick look if this can be avoided. But xts' merge() method is not fully compatible with zoo's, so it currently does not work. I'll investigate whether this can be improved.
Once I coerce it to be an zoo object (by as.zoo), it works.
Yes, that is recommended at the moment. Z
