Bug with x11(), Lion and CRAN R 2.13.1

Hello,

I have just installed R 2.13.1 on a clean install of Lion on a 3 year old iMac with a 2GHz Core 2 Duo. When I run R in the terminal and use the x11 device I get some strange behaviors when I call the dev.off() function. If I plot several times then usually I get the error:

    Error in dev.off() : parameter "i" in "mfg" is out of range

and if I plot only once I get the warning:

    Warning message:
    In dev.off() : Display list redraw incomplete

In both cases, a new x11 window opens (not exactly the expected result of dev.off). Steps to reproduce both cases are given below.

Also, it seems that the x11 device is not 3-4 times faster than the quartz device. Has anyone else noticed this?

Cheers,
Kjell

This is not peculiar to Lion: it does seem something about Apple's X11 
notifier and I've seen it quite often over the years on Leopard ...

Why would you expect it to be?  X11(type='Xlib') is, but that is no 
longer the default on OS X.

I had a typo in my original post, fixed below.

Oops!  That was supposed to say "the x11 device is now 3-4 times faster than the quartz device."  Anyway, here are the timings I get (I expected quartz to be the fastest but not for any particular reason):
