Here's a function that does that. I use to prompt the user to
choose among printing the current device with dev.print, saving
it with dev.copy2eps or continuing without doing anything. I
write my codes to use this function and then, depending on
whether or not the code is running from a script or not, I
redefine it with the tk version.

[R] calling R from a shell script and have it display graphics
Hello,
I am running R under Linux/x11.
I would like to call R from a shell script and have it display a series
of graphics.
The graphics should remain visible until the user clicks or presses a key.
I first tried R BATCH, but it does not load the x11 module, making it
impossible to open x11 or png devices.
Then, I tried to call R with a 'here' script:
R --vanilla --quiet --args text.txt 'EOF'
file=commandArgs()[5]
cat('processing ',file,'\n')
...
x11()
plot(f2,log='xy',type='b',las=1,cex=.5,xlab='rang',ylab='freq')
Sys.sleep(10)
q()
EOF
The problem with this approach is that the script cannot interact with
the user.
par(ask=T) will fail because it reads input from the script rather than
from the keyboard.
While I am writing this, a solution comes to my mind: I could save all
the graphics in png format (using R script.R), and when it is finished,
call ImageMagick's display to show all the png (or use any other
diaporama system). However, I find it a dirty hack.
Is there a simpler and cleaner way to achieve this?

Re: [R] calling R from a shell script and have it display graphics
How about saving to png and writing a small html file and then launching
a browser?
