all of a sudden my plots are not showed in the plot-window anymore, but in a separate window, which is quite inconvenient.
I already tried to restart the session, I tried dev.off() but that gives me the following error: Error in dev.off() : cannot shut down device 1 (the null device).
I also tried while (!is.null(dev.list())) dev.off(), but this didn't seem to change anything and lastly I tried graphics.off, this gave me; function ()
while ((which <- dev.cur()) != 1) dev.off(which)
but once again it still keeps opening a new window.
I cannot find what the problem here is, I hope that someone can help me!
Thanks a lot in advance!!
