Indexed 'tibble' and Methods for 'dplyr'

Provides extended data frames, with a special data frame column which contains two indexes, with potentially a nesting structure, and support for tibbles and methods for 'dplyr'.

Overview

dfidx used to offer support for tibbles and dplyr's verbs. It was actually a mistake because the user couldn't use dfidx and some packages like mlogit without installing many dependencies. The dfidx package is now free of any tidyverse dependencies and the tidydfidx package provides the complement. It re-exports:

• dfidx, idx, idx_name and fold_idx from dfidx,
• as_tibble, %>%, filter arrange, slice, pull, mutate, transmute and select from dplyr

provide relevant methods for dplyr's verbs and a print method for dfidx objects created from tibbles.

For a gentle and comprehensive introduction to the package, please see the package's vignette.
