What you say is interesting. 
> par("mar")
[1] 5.1 4.1 4.1 2.1

But why after restarting it came back?
Well, then it was gone and even if I restart all the computer, it never comes back.
So I’ve reset the PRAM (don’t know if it was a good idea) but now it works really great after many tries!

thank you!
