In R language, you can use the functions sort() or order() to sort in descending order. Here are some sample codes:

  1. arrange in order
vec <- c(5, 2, 8, 4, 1)
sorted_vec <- sort(vec, decreasing = TRUE)
print(sorted_vec)

Output:

[1] 8 5 4 2 1
  1. arrange()
vec <- c(5, 2, 8, 4, 1)
sorted_vec <- vec[order(vec, decreasing = TRUE)]
print(sorted_vec)

Output:

[1] 8 5 4 2 1
  1. Sort a column in a data frame in descending order.
df <- data.frame(name = c("Alice", "Bob", "Charlie", "David"),
                 score = c(90, 80, 95, 85))
sorted_df <- df[order(df$score, decreasing = TRUE), ]
print(sorted_df)

Output:

     name score
3 Charlie    95
1   Alice    90
4   David    85
2     Bob    80

Please note that in the sort() and order() functions, descending sorting can be achieved by setting the parameter decreasing = TRUE.
