arrange-methods: Arrange rows by column values

In stemangiola/tidybulk: Brings transcriptomics to the tidyverse

Arrange rows by column values

Description

'arrange()' order the rows of a data frame rows by the values of selected columns.

Unlike other dplyr verbs, 'arrange()' largely ignores grouping; you need to explicit mention grouping variables (or use 'by_group = TRUE') in order to group by them, and functions of variables are evaluated once per data frame, not once per group.

Arguments

.data	A data frame, data frame extension (e.g. a tibble), or a lazy data frame (e.g. from dbplyr or dtplyr). See *Methods*, below, for more details.
...	<['tidy-eval'][dplyr_tidy_eval]> Variables, or functions or variables. 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.

Details

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

## Missing values Unlike base sorting with 'sort()', 'NA' are: * always sorted to the end for local data, even when wrapped with 'desc()'. * treated differently for remote data, depending on the backend.

Value

An object of the same type as '.data'.

* All rows appear in the output, but (usually) in a different place. * Columns are not modified. * Groups are not modified. * Data frame attributes are preserved.

A tibble

Methods
