[R] Pasting a large chunk of R code in terminals

[jim holtman]

Another good reason for using "source" instead of copy/paste is that if an
error occurs, the 'sourced' script will stop at the error, while the
copy/paste will keep on chugging away, knowing who does what in the rest of
the script.  Most of the editors I have used on Windows (notepad++, tinn-r)
support highlighting code and then automatically creating a temporary file
that is 'sourced' in.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
