split_factors: Split a data frame by factors

Description

Split a data frame into subsets grouping by one or more factors.

This function is used to split a data frame into a named list where each element is a level of the grouping variable (or combination of grouping variables).

Usage

split_factors(.data, ..., keep_factors = FALSE)
as.split_factors(.data, keep_factors = FALSE)
is.split_factors(x)

Value

A list where each element is a named level of the grouping factors. If more than one grouping variable is used, then each element is the combination of the grouping variables.

Arguments

.data

The data that will be split. Must contain at least one grouping variable.

...

Comma-separated list of unquoted variable names that will be used to split the data.

keep_factors

Should the grouping columns be kept?

x
