[R] Need Help!

[dawood ahmad]

Dear Sir/Madam,
 
I hope you will be fine. I am new to R language. Recently, I am trying to fit my data with one model.
I am sending you the code and image file on which you can see the error I am receiving instead of executing.
If I give a single value to parameter "ep", it executes well, but if I make a loop/seq for getting a range of data it shows
error.I need you help in solving this problem.
 
Thanking in advance,
 
With Best Regards,
Dawood
