No, its since you are using a differnt source package name than the
binary package.  In file

  https://salsa.debian.org/r-pkg-team/dh-r/blob/master/dh/R.pm

  148        open(my $svs, ">>", "debian/$sourcepackage.substvars");

the substvars are moved to debian/$sourcepackage.substvars which
is just wrong.

Niels, I'm not a Perl programmer and to lazy to dive into the
debhelper module.  Could you please point me to the way how to
use the mainbinarypackage name there (usually R packages have
only one binary package - so the first binary package name will
solve the issue.

Kind regards

       Andreas.
