dplyr Arrange

Introduction

The arrange() function sorts data frames by one or more columns. It's essential for data organization.

Basic Sorting

library(dplyr)

df <- tibble(
  name = c("Charlie", "Alice", "Bob"),
  score = c(78, 85, 90),
  age = c(35, 25, 30)
)

# Sort by single column
arrange(df, score)

# Sort descending
arrange(df, desc(score))

Multiple Columns

# Sort by multiple columns
arrange(df, age, score)

# Different directions
arrange(df, desc(age), score)

Using Pipes

df %>%
  filter(score > 80) %>%
  arrange(desc(score)) %>%
  select(name, score)

Summary

arrange() organizes data by sorting. Use desc() for descending order and multiple columns for complex sorting.
