[R-pkg-devel] How do you make it possible to run the example that requires a Conda environment?

[Brian G. Peterson]

\dontrun{} is allowed by CRAN.  If your package got rejected for using
\dontrun{} I would guess that maybe your example needs a package that
isn't in "Suggests" in your DESCRIPTION file.  Even in \dontrun{} you
should still tell the user that certain packages may be needed to
access specific optional functionality.
