I installed R 2.14.1 on a OSX 10.7.2 computer using MacPorts. If I fire up
R on a terminal, this very simple session gives me errors. I attach
sessionInfo() details as well. In addition to the warnings, I also do not
get any plots on the X11 window after the warnings. So one cannot just
ignore the warnings since the plots don't work anymore after this. I guess
one could try to avoid this by not overwriting the plots, but it should not
lead to errors fatal to the X11 graphics output of the R session. Is this
reproducible on other machines and is this a bug?
Thanks!
