you don't.  Use R ! ..

Well, I'm mostly joking.  Personally, I do use Rstudio very
rarely (but R daily, 85% of my work time), but then I'm a
co-author of ESS (Emacs Speaks Statistics) and have been an
emacs lover since ~1988 ..

It's good, Luigi, we (all R-help readers) now know about the problem.
But this mailing list is about R (and the R project). Rstudio is
a company and a product has their own support list.
Though I'm sure they will get the message from here or otherwise

Do keep using Linux, it's well worth the occasional small
pain.  It allows you to smell the true original fresh air if you
want instead of having to breathe continuously being wrapped
inside  sugar candy.
At home and at work, I have no computer but those running Linux
(even though I'm occasionally glad to have access to a Windows
 terminal server at work, not the least to test R and packages,
 almost always using ESS also there)!
