My df looks like this now.
A B C
1 3 .
1 6 .
1 9 .
2 1 .
2 2 .
2 5 .
3 9 .
3 3 .
3 2 .
Below is the ideal dataframe I am try to create:
- Variable A refers to individuals (user-id). Each individual has three rows.
- Each individual has different values for variable B...
- whereas they need to have a same value of variable C.
I need to repeat a same value of variable C for each individual. I was wondering how I can give each participant the same value of variable C so that variable C is repeated three times for each participant.
A B C
1 3 1
1 6 1
1 9 1
2 1 3
2 2 3
2 5 3
3 9 8
3 3 8
3 2 8
