Split a data frame into subsets grouping by one or more factors.
split_factors(.data, ..., keep_factors = FALSE) as.split_factors(.data, keep_factors = FALSE) is.split_factors(x)
.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 | An object to check for class |
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.
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).
split_factors()
Split a data frame by factors.
as.splict_factors()
coerce to an object of class split_factors
is.splict_factors()
check if an object is of class split_factors
