Assume you want to execute code in 'mycode.R', the easiest way is:
echo "source('mycode.R')" | R --vanilla --quiet
If you do it in a shell script, you can also pass variables to your code
like this (list of shell script):
#!/bin/sh
echo "var1=${1};var2=${2};source('mycode.R')" | R --vanilla -- quiet
Good luck,
Oleg
