I also tried to only duplicate when `"dimnames

You mention "xts methods". Are there any methods other than `timeBasedSeq` (which you mentioned in [your StackOverflow question](http://stackoverflow.com/q/36127951/271616)) that should have this feature?

@poglio the `multi.panel` argument is only available in the latest version of xts on GitHub. It is not yet on CRAN.

To clarify, this works with matrix and zoo objects because `[[` with character `i` matches on rownames (technically, `dimnames(x)[[1]]`), but xts objects do not have rownames. ``` r > sample_matrix[["2007-06-28",1]]...

Note that none of these error with zoo. ```r # no column names z

It also ignores `par(yaxt = "n")` and `par(new = TRUE)`.

Thanks for the feedback, @steven001. There is no `names.xts()` method, so the `names.zoo()` method is being called. And it looks like xts behaves the same as zoo in this case....

This is because `merge.xts` is called if the two indexes are not identical, and `merge.xts` does not currently support `check.names = FALSE`. Current xts behavior is also inconsistent with zoo...

You're more than welcome to try, but I have to warn you: I'm going to be extremely critical of any patch(s) that attempt to change `merge.xts` (either in the R...

@fcasarramona That's not really another form. It's what I said in my initial comment: `merge.xts` does not current support `check.names=FALSE`. The different index value in your second example is expected....
