Header = TRUE problem - solved

I am very new to R, and

I was practicing to import a .txt file to R (using an example on the book I read), and I used header = TRUE.
I was trying to convert the variable 'job' into a factor variable, however, R seems not knowing the first row are names of the variables.

Here is the error message I received, can anyone help me please?

Got it. In case someone has the same confusion.
