arrange()Sometimes it is helpful to sort data, alphabetically or numerically, using the arrange() function from dplyr.
To arrange all penguins, in order of increasing bill length:
penguins %>%
arrange(bill_length_mm)## # A tibble: 344 × 8
## species island bill_length_mm bill_depth_mm flipper_length_mm body_mass_g
## <fct> <fct> <dbl> <dbl> <int> <int>
## 1 Adelie Dream 32.1 15.5 188 3050
## 2 Adelie Dream 33.1 16.1 178 2900
## 3 Adelie Torgersen 33.5 19 190 3600
## 4 Adelie Dream 34 17.1 185 3400
## 5 Adelie Torgersen 34.1 18.1 193 3475

## 9 Adelie Torgersen 34.6 17.2 189 3200
## 10 Adelie Biscoe 35 17.9 190 3450
## # … with 334 more rows, and 2 more variables: sex <fct>, year <int>In order or decreasing bill length:
penguins %>%
arrange(desc(bill_length_mm))## # A tibble: 344 × 8
## species island bill_length_mm bill_depth_mm flipper_length_mm body_mass_g
## <fct> <fct> <dbl> <dbl> <int> <int>

## 10 Chinstrap Dream 52.8 20 205 4550
## # … with 334 more rows, and 2 more variables: sex <fct>, year <int>For text data, dplyr will arrange alphabetically.
