Summary --- testing for existence of file.
...ho answered my question about how to test
for the existence of a file: Berwin Turlach, Jari Oksanen, Henrik
Bengtsson, Uwe Ligges, and Joerg Maeder.
The simplest solution is to use the built-in (!!!) function
file.exists() which returns TRUE if the file exists, and FALSE
if it doesn't. Like, duhhhhhh!!! It's exactly what I wanted.
Special thanks to Berwin Turlach who explained to me how I might
have found out about file.exists() for my own self ---
> 1.) In R type help.start().
> 2.) Go to browser and select "Search Engine & Keywords".
> 3.) Enter "file"...
