I have a dataset including a variable named "code". I format it as type "character".
This variable contains such observations like G4411, H5551, K9878..
Now I want to extract the first character out of every observation.
This means G4411 –> G, H5551 –> H, K9878 –> K
I have also attached the data file at the end of the post!
Could somebody help me with this problem?
Many Thank and best regard!
