metan (version 1.7.0)

doo: Alternative to dplyr::do for doing anything

Description

Provides an alternative to the dplyr:do() using nest(), mutate() and map() to apply a function to a grouped data frame.

Usage

doo(.data, .fun, ...)

Arguments

.data

a (grouped) data frame

.fun

A function, formula, or atomic vector.

...

Additional arguments passed on to .fun

Value

a data frame

Details

If the applied function returns a data frame, then the output will be automatically unnested. Otherwise, the output includes the grouping variables and a column named "data" , which is a "list-columns" containing the results for group combinations.

Examples

# NOT RUN {
library(metan)
