The usual R-help etiquette recommends:
1. questions about packages go to the maintainer, not to R-help.
2. examples should be reproducible: ie self contained.
if you look carefully at the function latex.summary.rqs you will see
that there is a failure to pass the argument "..." on to
latex.table. This
_may_ be the source of your problem if in fact your v1 and v2 were
summary.rqs objects, but I doubt that they are.
You might try caption = "". More generally there are much improved
latex tools elsewhere in R; if you aren't making tables that are
specific
to quantreg, you might want to use them.
