Flag --interactive is only in 2.7.0.  There is no simple way to get
2.6.2 to accept input redirected from a script and run the event loop on
which
X11() depends.  (One non-simple way is to write an alternative front
end.)

You need to ensure that the script does not exit, which will close the
device (not just delete the plot).  Sys.sleep() may not be sufficiently
flexible -- one idea is to use locator() to get the viewer to click on
the plot when done with it.

Another route is to generate the plot as, say, a PNG file and launch a
separate viewer to show that via system(wait=FALSE).
