As we executed a basic output-oriented CCR DEA model (or alternatively an output-oriented BCC DEA model), the plots obtained are: (1) bar plot of the number of efficient and inefficient DMUs, (2) distribution of the efficiency score of the inefficient DMUs, (3) horizontal bar plot of the number of times that efficient DMUs appear in the peer set of the inefficient DMUs, and (4) the references chart. The graphical results also depend on the selected model. Other popular R packages (with more than 10,000 downloads from ) are Benchmarking, nonparaeff, rDEA, DJL, and deaR. One of the first R packages is FEAR and it is the first DEA software that includes functions for running the bootstrap methods proposed in. In recent years the contribution of R packages to estimate efficiency has increased significantly, and a wide variety of DEA models can be applied. Data Envelopment Analysis is no exception. Those packages contain applications in almost every scientific field, e.g., Biology, Finance, Data Science, Meteorology, etc. Currently (as of 2020), there are more than 16,000 user-contributed packages available at CRAN (Comprehensive R Archive Network). One of the greatest strengths of the R programming language is in the ease of creating extensions through packages contributed by a constantly growing user community. Regarding non-commercial software, one of the alternatives that has had the greatest growth in recent years is the programming language R (it is a programming language and free software environment for statistical computing). The main drawback we see in all these software options is commercial software and their access is therefore limited for many practitioners. It should also be mentioned that some of the most popular software used by mathematicians, engineers and econometricians-such as GAMS, STATA, SAS or Matlab-have also incorporated modules to estimate efficiency through DEA models (for example: ). MaxDEA offers two versions to users: (1) MaxDEA Basic, which allows running basic models (CCR, BCC, Slacks Based Model and Cost model) under different orientations (input, output and non-orientation) and returns-to-scale with no limit of DMUs, and (2) MaxDEA Ultra, the commercial version in which a wide variety of models are available (a list of them can be consulted at: (accessed on 12 June 2021)). It is worth noting the great diversity of models implemented in MaxDEA ( (accessed on 12 June 2021)), which is developed with VBA Access. More recently, Daraio, Kerstens and Cavalcante conducted a comprehensive review of current software options for productivity and efficiency analysis and carried out a comparative analysis on them.
