I would like to know if and how I can detect unique values of one
variable and write them into a new variable.
For Example:
Country
Australia
Australia
Belgium
Belgium
Germany
I need a variable which is:
unique = "Australia" "Belgium" "Germany"
I don't need:
unique = "Australia" "Australia" "Belgium" "Belgium" "Germany"
Thank you!
