[hd-deman]

@hd-deman thanks for getting back so quickly.
I was thinking of @jimhester's lintr package, which I find quite good.
I haven't systematically compared R linters though, I just came across (and liked) lintr, because it is already implemented for Sublime Text.

I guess formatR would be a different beast, since that actually changes (rather than lints) code.

lintr has nearly all of the functionality of the existing R linting packages, (lint and svtools were the main ones I was aware of), plus many more.

r-lib/lintr#42 is for adding Atom integration (we already have Vim, Emacs, Sublime Text, RStudio).

It shouldn't be too much work to get Atom integration working if you base it off of the existing integrations.

I haven't done so yet because I do not use Atom myself and I wasn't sure how popular it was for R users, but at least different people have now requested it, so it is probably worthwhile.
