sort a data frame based on multiple columns in R
This question already has an answer here:
To sort in ascending order:
Use dplyr like this:
library(dplyr)
df <- df %>% arrange(type, frequency, word)
Just arrange the variables in the order you would like to sort.
To sort in descending order:
Just use a negative sign in front of the variable you want to sort in reverse order. Like this.
df %>% arrange(-type, frequency, word)
Working with text...
If you want to try sorting text in reverse order using the method above, you may get an error. To arrange categorical variables, wrap the variable around desc(), as such:
df %>% arrange(desc(word))
