Help! Weird behavioral difference between R interactive and command-line?

Hi all,

This weird problem has been bugging me for a while.

If I run the R program in an interactive session, it worked;

But if I run the R program on command-line, it stopped with no reason: with
"Execution halted" message and without any specific error messages.

What could be the problem?

Thanks a lot!

I've given you my standard links about reproducibility before so I
won't repost them here (I'm also on someone else's computer after a
recent move), but does this even begin to look like a reproducible
example?

You will have to **show** what you did; it isn't sufficient to
**describe** what you did.


The problem could be that somewhere in your program there is something
that only works in an interactive session.

The problem could be that your "command-line" attempt is using a
different
working directory than your interactive session.


You could insert some sort of print() statements in your program to try to
find out how far it runs before it halts, which might give you a clue as
to what the problem is.

Hi

some functions, like plot, readline and others behave
different depending to the result of the function interactive() 

there is no way to ask R which functions do that
