You have failed to provide the most basic of information as requested in
the posting guide. As you mention 'i create a x11 window and plot' I will
assume you mean that you open an X11() device and hence this is some
Unix-alike OS.
This has come up several times before, so please search the archives. If
you 'popen' R, its input is not from a tty and so it is not considered to
be running interactively and hence is not expecting users to interact with
it (like shutting down windows).
R 2.7.0 allows a --interactive flag which may help. Exactly what the
circumstances are in which the event loop is blocked seem to be
system-specific. But normally if non-interactive R is reading from stdin
it is completely blocked until input is completed -- and that is not
usually the case if R is interactive.
Should this be Windows (which does have an x11() device), the relevant
flag is --ess.

i have created a wrapper C++ class that popen()s R. When i create a x11
window and plot, i cannot close it using the window button. Also, when i
minimize or maximize the window, the plot does not redraw. Can anybody
tell me if there is a way i can get back this window functionality or if
it is not possible?
thank you kindly.
