Overview

dfidx is a small R package which is intended to deal efficiently with data frames when each observation is identified by a combination of values of two variables (indexes). dfidx exports the function dfidx which takes as main argument a data frame and returns a dfidx object and the idx/idx_name functions which respectively return one or all of the indexes and their names. Methods are provided for R's extractors and for some of dplyr's verbs.

Installation

dfidx is on CRAN. Use\ : install.packages("dfidx").
