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
