hi everybody,

today  I  decided  (unwisely,  it  appears) to install 2.7.0
under MacOS 10.4.7. now, when I  run  R  from  the  terminal
command line and do something like

plot(1:10)

a  X11 graphic window pops up, the 10 points are drawn on an
otherwise blank canvas (no axes, no labels, no  ticks  etc),
CPU  time  goes  to 100% and stays there and R does not come
back to the prompt ("hangs"). I tried to `ktrace'  this  but
this  produced a one Gig logfile in a few seconds from which
a learned nothing ...

a quick search of the  archive  did  not  yield  a  hit.  so
please: what's going on here?

thanks a lot for this "real time" response.

Ancient system? As a very first step for your own good I'd recommend  

well, no. actually I _have_ 10.4.11 installed (I somehow was sure it's 10.4.7,
still. that's probably alzheimer casting his shadow :-)).

updating your system which is way out of date (the current version  
Tiger is 10.4.11). Then if the issue persists, please report your full  
sessionInfo() and machine used. The above works without problems on  
both 10.5.2 and 10.4.11 (Mac Pro and iMac).

10.5.2 is no option for me since I need a working fullscreen X11 mode.
I now checked it again both on a dual 2Ghz G5 PPC and a 1.5 GHz power book PPC G4, 
both running
10.4.11: same problem. actually, R hangs only when really plotting. so
I can first open the device with X11() and get back to the R prompt. only
when executing the `plot(1:10)' R apparently hangs and everything is as described
in my first mail.

here comes the session info:

R version 2.7.0 (2008-04-22) 
powerpc-apple-darwin8.10.1 

locale:
C/de_DE.ISO8859-15/C/C/C/C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] micropet_1.7.0 psflib_1.0     pkc_1.1        fzrutils_1.3   roiutils_1.3  

(identical on both machines).

any hint/help really appreciated.

regards,

joerg
