You might like to checkout r-cran-shiny[1] or look directly at the
linktrees file[2].

I can't exclude that it is just my fault. ;-)

Yes.  Due to your hint I'm now using only one remaining dir replacement
and I needed to use embed here (see [2]) - otherwise the package fails
to build with the above error.

However, what now converns me even more is that when using the replace
action the dependencies are missing in the resulting control
DEBIAN/control inside the package.  It looks like:

  Depends: libjs-jquery-ui (<< 1.10.1+dfsg.0~), libjs-jquery-ui (>= 1.10.1+dfsg), r-base-core (>= 3.2.4.20160412-1), r-api-3, r-cran-httpuv, r-cran-mime, r-cran-jsonlite, r-cran-xtable, r-cran-digest, r-cran-r6, r-cran-htmltools

So the embed triggers the (unwanted) strong dependency and the replace
triggers no dependency from the other libs.  So most probably I did
something really wrong here - but I wonder what?

Kind regards

       Andreas.
