[ESS] Installing, testing various ESS, does roxygen -> html work for you?

[Sparapani, Rodney]

 I'll just tackle this one...

No.  Depending on where it is...

If it is in default.el, then emacs --no-init-file avoids it (and .emacs too)
If it is in site-start.el, then emacs --no-site-file avoids that.
And of course, emacs --no-init-file --no-site-file ignores everything.

Thanks,

Rodney
