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updating your system which is way out of date (the current version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

Hmm - I have tried even the PowerPC version now and it works without  
problems for me.
Are you using Apple's X11 or something else? Also do you get the error  
in the "regular" (non-root) mode?

Thanks,
Simon

I'm still experiencing problems with cairo-based graphics and 2.7.0.: 

while the problem somehow went away on my powerbook g4 after having once
explicitly used `x11(type="Xlib")',  i.e. even after restart of R now plotting
procedes as it should, the same procedure was not successful on my tabletop ppc g5 (both
machines with macos 10.4.11.). here the problem persists as described in my
first mail: any plotting command, e.g.

plot(1:10) 

to the default x11 device (i.e. with type = "cairo")
plots only the data points on an otherwise empty canvas, then cpu time goes to
100% and R does not come back to the prompt ("hangs"). at which stage I can only
kill R, e.g. by throwing away the terminal running R.

I hvae not the slightest idea what can go wrong specifically on my machine. any
suggestions what (and how) to log or where to look greatly appreciated.
