[R] 'strange' R graphics problem | Linux...

[Evan Cooch]

So, am running 3.2.2 on a Centos 6.xx box. Code executes fine, but I'm 
having a heck of a time with graphics. I don't think this is related to 
R in the broad sense, but how it is interacting with graphics on the 
system. here is a description of the problem.

1\ something simple:  test <- rnorm(100)

2\ try to generate a simple histogram  using hist(test)

3\ what happens is that a terminal window pops up (as I would expect for 
the graphic), but rather than showing the histogram, its essentially a 
screen-capture of the original terminal window in which I ran the 
script. Said second terminal window is not responsive, at all -- can't 
even close it short of opening another shell, and killing the process 
from the CLI.

4\ I get the exact same problem even if I try  a simple plot.new() -- 
generate a new terminal window, but with the same problem 'attributes' 
as described above.

For what it works, when I fire up gnuplot, terminal type set to X11 -- 
and basic gnuplot graphics (e.g., plot sin(x)) work perfectly. Other 
graphics seem to work fine too. Just nothing I try to plot using R.

Anyone have any ideas as to what to look for/try? Here is the output of 
sessionInfo() -- nothing obvious that I can see.
