I'm kind of a beginner on Rstudio, and I have this problem :
I have a data wich is the result of mass questionning from an institute (7825 people).
I want to recode variables to change names (for exemple, instead of 1 or 2 on the question about the gender, I want to have man or woman). I have no problem to do it, but then when I want to use it with another function, I get this error message :
Erreur : Can't subset columns that don't exist.
x Columns NA, etc. don't exist.
I join a screen of my code so you can see clearly, and as you can see on it, there is no problem with the function until I use my recoded variables.
Thanks for your time !
