Hey Joachim, thank you so much for the nice video.😊I still have a quesion. I have a categorical variable questioning how person got his environmental knowldge and I have categories like (School, Media, Mass Media and so on) The problem is that the dataset shows every category as a separate binary category and I wanted to combine them all into one categorical variable.I do not know how to do it and I tried to apply this code in the video but I could not succeed :(

Thank you soo much

Hi, hope you can help me with this error:
I'm trying to combine a number of symbols into a group, for examples, the data is like this:
1. AF
2. AF
3. BI
4. BI
5. CP
6. CP
but I don't know why when I use the function levels(), the result is something like:
"CP" "AF" "BI"
It's not the order I wanted
Is there any way to fix the error? please help me, thank you.
