Dear all, 

I have a data set with 260 rows for 36 different subject.
All subject are identify by their name, a string variable.
I would like to create a variable "id" with value 1 for the fist subject,
value 2 for the second ... until 36

Name  id 
Alli	1
Alli 	1
Alli	1
Bear	2
Chea	3
Chea	3
.
.
.

How can I do ?

Thank you 

Alvine
