I am working with the AddHealth dataset and I need to turn some variables into one. For example, I need to combine the numbers 1 and 2 and say that both numbers represent the number one, for each of my columns.
I want to turn this
H1RP1
1- Strongly Agree
2- Agree
3- Neither
4- Disagree
5- Strongly Disagree
Into this
1- Strongly Agree+Disagree
2-Neither
3-Disagree + Strongly Disagree
How can I do that? Thank you in advance!
