## Overview

deaR is an R package for conventional and fuzzy Data Envelopment Analysis. Its principal workflow is to obtain DMU data, construct a DEA data object, run a model, then extract and inspect efficiency results. The README documents that sequence and names additional analysis capabilities; source excerpts were unavailable, so links among those additional capabilities are omitted where their wiring is not established.

Main entry points: [`R/efficiencies.R`](https://github.com/elseviersoftwarex/softx-d-25-00164/blob/master/R/efficiencies.R) (Efficiency scores), [`data`](https://github.com/elseviersoftwarex/softx-d-25-00164/tree/master/data) (Example datasets), [`R/model_basic.R`](https://github.com/elseviersoftwarex/softx-d-25-00164/blob/master/R/model_basic.R) (Conventional models), [`R/modelfuzzy_kaoliu.R`](https://github.com/elseviersoftwarex/softx-d-25-00164/blob/master/R/modelfuzzy_kaoliu.R) (Fuzzy models)
