I am a newbie and can't figure out how to recode a numeric value. In my data (pharm311), I have a column called "explain" and I need to find all the 6's and change it to NA (blank). Could someone help?
is.na(pharm311$explain) <- pharm311$explain==6 And do note: NA is not the same "blank". It is "missing".
I'm sorry if this is too basic, I started messing with R this week and got stuck with this problem since yesterday...
