...at least I think that is what happens, at least on some
configurations. Here's a repeatable example:
cd R_HOME/tests/Embedding
touch tmp.R
make tryEval
and then (correct)
> ./tryEval --slave
Error in sqrt("") : Non-numeric argument to mathematical function
Caught an error calling sqrt(). Try again with a different argument.
[1] 3
versus (non-interactive; no return)
> ./tryEval --slave < tmp.R
Error in sqrt("") : Non-numeric argument to mathematical function
Execution halted
> echo "sessionInfo()" | R --slave
