This will be a quick one. I was trying to sort my dataframe so that it went in ascending order on one variable and descending order on another variable. This was really REALLY bothersome to try to figure out with base R functions. Then I remembered sqldf!
# Assuming dataframe named 'mydf' and 'V1' and 'V2' are your variables you want to sort on in opposite directions library(sqldf) mydf.sorted = sqldf("SELECT * FROM mydf ORDER BY V1 ASC, V2 DESC")
That’s all! No pain, and lots of gain. Show me how to do this so simply with base R and I’ll be impressed.
After many comments on this post, it’s become painfully obvious to me that I wasn’t using the right search terms (or looking at that negative sign on the second argument to the order function) when searching for a base R solution to this problem. Well, we all make mistakes, right? I hope this post has still been helpful to others, and it isn’t a completely redundant internet resource on this topic!
