"GUI" and "batch" are incommensurable to my mind... A batch run is
something that might get executed in the middle of the night. You mean
start GUI from a shell script? For Tcl/Tk there's a slightly ugly hack
along these lines:

#!/bin/sh
R -q --vanilla << ___EOF___ > /dev/null
library(tcltk)
tkpack(tktext(tktoplevel()))
tkwait.variable("foo")
___EOF___
