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.
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.
