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.
dfidx is on CRAN. Use :
install.packages("dfidx").
To install the developping version, use :
remotes::install_github("ycroissant/dfidx").
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
