I wrote previously about recoding characters into numbers using various coding schemes and about recoding numeric values into characters in 2017, where I covered, the recode() function. In this tutorial, I will compare recoding methods with ifelse(), recode(), case_when() and case_match().

I often find myself needing to recode variables. I wrote previously about recoding a characters into a numbers using various coding schemes. But sometimes I want to recode numeric values into characters; this is particularly useful for graphing and for double-checking the meaning of your variable levels.
