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?
