nest_relocate: Change column order within a nested data frame

In nplyr: A Grammar of Nested Data Manipulation

Change column order within a nested data frame

Description

nest_relocate() changes column positions within a nested data frame, using the same syntax as nest_select() or dplyr::select() to make it easy to move blocks of columns at once.

Usage

nest_relocate(.data, .nest_data, ..., .before = NULL, .after = NULL)

Arguments

.data	A data frame, data frame extension (e.g., a tibble), or a lazy data frame (e.g., from dbplyr or dtplyr).
.nest_data	A list-column containing data frames
...	Columns to move.
.before, .after	Destination of columns selected by .... Supplying neither will move columns to the left-hand side; specifying both is an error.

Details

nest_relocate() is largely a wrapper for dplyr::relocate() and maintains the functionality of relocate() within each nested data frame. For more information on relocate(), please refer to the documentation in dplyr.

Value

An object of the same type as .data. Each object in the column .nest_data will also be of the same type as the input. Each object in .nest_data has the following properties:

• Rows are not affected.

• The same columns appear in the output, but (usually) in a different place.

• Data frame attributes are preserved.

• Groups are not affected.

Examples

gm_nest <- gapminder::gapminder %>% tidyr::nest(country_data = -continent)

gm_nest %>% nest_relocate(country_data, year)
gm_nest %>% nest_relocate(country_data, pop, .after = year)
