The easiest way to get that message is to execute return() from the top
level:

> return(1)
Error: no function to return from, jumping to top level

so a good guess is that you (Tolga) might be trying to return() from
source()d file. Or maybe source()ing something that was intended to be
inside a function body (extraneous '}' characters can do that).
