incomplete final line found on <name of my sourced function file>

Dimitri.

This has been asked a whole bunch of times on this list. Do a search on the
text in the error message if you doubt me. I have this link on my toolbar:

Try opening the file up in a text editor and inserting a blank line or
two on the end. (There's either an EOL or EOF character missing and
this trick usually works for me -- never sure why/when it happens
though)

Dear R-ers,

I hope there is a really simple solution to my problem.
I've written a function that I saved in an .r file. I source this file
in my code. For a while it worked fine. But then when I run the line:

source("F mylineplot.r")

I started getting a warning:
In readLines(file) : incomplete final line found on 'F mylineplot.r'

I have no idea why - I tried to check and to recheck what's going on,
but am not finding anything.
The code works both when I try to run it NOT as a function and when I
run it AS a function. So why the warning message?

Just in case - the text of my function inside my file that I source. I
really don't expect anyone to dig into it - but maybe something will
jump at you?
Thanks a lot!
Dimitri
