Hi, I search how to replace my "NA" in my database by real NA. For this i use this code :
commun <- commun %>% mutate(across( .cols = everything() , .fns = ~ gsub("NA",NA, .x)))
but in my data if a name or surname contains NA like "NATACHA" or "PANACOTA", it is also change as a NA, and I don't want this. Do you know how can I subset only when we have the full word, with no letters before of after "NA"
Thank you for your time.
