You're not missing anything.
In your output.Rout: the ">1" right after the source('test') is the
"1" inputed from answers.R. the "[1] 1" is the result of test. Remove
the second line from answers.R and see what happens (hint: script ends
after the readline prompt).
Just out of curiosity, why will you use a script that requires user
input (readlines) in batch mode ?
Cheers
