Dear Nezahat
In future it would be helpful if you

1 - gave us the data so we can reproduce what you are doing
2 - told us what the error was in case we cannot replicate ti
3 - did not post in HTML as it messes up everything in your post

What did you think x1 <- numeric was going to do?
Try
x1 <- numeric
str(x1)

I am trying to find out statistical significance difference between these categorical levels for each variable, but my  function is not working! Please note that my data "x" are in data.frame format.
