ReaperPlugins via Arch User Repo - will they fit to audacity?

I am on a Manjaro-Linux, which is a fork of Arch-Linux. In the Arch User Repo there is a Build of the “Reaper Digital Workstation”. If I install this, there will also be lots of effects installed.
Will these effects be available in Audacity?

If not, how can I get superior quality plugins for Compression, Gating and Equalizer, similar to those of Reaper? I have not found similar plugins in the Web.

I don’t use Reaper so I can’t comment on that.

You could try the Calf plug-ins.
You could try the Guitarix plug-ins.
