[rkward-devel] dev.off () bug

[Prasenjit Kapat]

Calling dev.off() creates a new cairo device instead of closing the
existing one:

> plot (1,1)
> dev.off()
Warning message:
In dev.off() : Display list redraw incomplete
X11cairo
       4

Now, calling dev.off() twice closes the two devices.

> dev.off()
X11cairo
       3

> dev.off()
null device
          1

This doesn't happen if x11() is called explicitly:
> x11 ()
> plot(1,1)
> dev.off()
null device
          1

x11(type='Xlib') or x11 (type='cairo') or x11(type='nbcairo') behave
fine as well (ie when called explicitly before plotting). Other
devices: pdf () or png () (and hopefully others) work fine too.

I am working with the current svn.
