R is a collaborative project with many contributors.
Type    "?contributors" for a list.

Type    "demo()" for some demos, "help()" for on-line help, or
        "help.start()" for a HTML browser interface to help.
Type    "q()" to quit R.

R_INFILE 
"foobar"

etc at least under Unix (which I presume is where you are if you want to
use a shell script)
