R: Arrange rows by variables

arrange {dplyr}

R Documentation

Arrange rows by variables

Description

Use desc() to sort a variable in descending order.

Usage

arrange(.data, ...)

## S3 method for class 'grouped_df'
arrange(.data, ..., .by_group = FALSE)

Arguments

`.data`	A tbl. All main verbs are S3 generics and provide methods for `tbl_df()`, `dtplyr::tbl_dt()` and `dbplyr::tbl_dbi()`.
`...`	Comma separated list of unquoted variable names. Use `desc()` to sort a variable in descending order.
`.by_group`	If `TRUE`, will sort first by grouping variable. Applies to grouped data frames only.

Value

An object of the same class as .data.

Locales

The sort order for character vectors will depend on the collating sequence of the locale in use: see locales().

Tidy data

When applied to a data frame, row names are silently dropped. To preserve, convert to an explicit variable with tibble::rownames_to_column().

Examples

arrange(mtcars, cyl, disp)
arrange(mtcars, desc(disp))

# grouped arrange ignores groups
by_cyl <- mtcars %>% group_by(cyl)
by_cyl %>% arrange(desc(wt))
# Unless you specifically ask:
by_cyl %>% arrange(desc(wt), .by_group = TRUE)
