This? What was "this"? In my opinion, indefinite pronouns should be
banned from discourse when discussing computer programs.

There still appears to be confusion about data files and scripts. Do
you have both?
I was asking about the file that you were hoping to read with the
read.table command. Please stop referring to creation of scripts. The
read.table command is not to be used for accessing scripts. Only
source() would be so used
Again. Please produce the original code you used to create the file
which you are hoping to access using read.table.
> The script file name is Ross.R
Which is of no interest to us unless you named a data file
incorrectly. We still would need to know HOW it was created. What
were the commands? What was in it?
