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.
