[R] Why doesnot Rscript work ?

[Romain Francois]

Hi,

Rscript is meant for non-interactive use, so the default device is not 
the same as when you run R.

If you really want a window, open it yourself by calling the appropriate 
function (X11, windows, ... ) or reset the "device" option to whichever 
device you want to use, but it will disappear at the end of the script, 
so not very interesting.

You probably should open a png device or something and then write the 
grap there.

See ?png, ?pdf, ?X11, ?options, ?Rscript
