I need help !
I have one nominal variable (x1, composed by 6 numbers) that i would like to transform into another (x2) which will be the name of different companies. It is the first four figures which will indicate to me what is the company. For example, if x1 = 543400 I would like that x2 = "Ecyton" because the header " 5434 " corresponds to this company.
Have you ideas how to realize this manipulation?
Thank you in advance
