[R] Tunnelling X for R graphics

[Adam D. I. Kramer]

Thanks very much for the reassurance.

Really, I can just open a new X11 device on the same display, since the
display (localhost:10) is effectively "reconnected" when I ssh in again.

I'll reply again to this post if I find other parts of R working poorly
after the disconnection.
