[R-pkg-devel] How to avoid R CMD check warning for documentation of non-package functions?

I haven't tried this, but I believe if you define functions with the
right name and header in your package but don't export them the warning
will go away.

If that doesn't work (or defining those causes other issues), a more
involved workaround would be to change the \docType{} declaration for
the help page.  \docType{package} is the most free-form, but you might
get warned if you have two of them.  \docType{data} might be flexible
enough.  If you do this, you won't use \usage{} or \arguments{}, you'll
put together your own sections using \section{Usage}{ ... } and
\section{Arguments}{ ... } and try to get the formatting right.
