Build (standard) DEA problem using ROI infraestructure
This function works like dea but without strict parameter check.
roi_dea(input, output, orientation, solver)
input: A matrix or a data frame containing the inputs of the units to be evaluated, with one row for each DMU and one column for each input.output: A matrix or a data frame containing the outputs of the units to be evaluated, with one row for each DMU and one column for each output.orientation: Use "input" for input orientation or "output" for output orientation in DEA model. The default is "input".solver: a solver to be used by ROI to solve the DEA optimization problem. Use ROI_installed_solvers() to list them.list(lp, status, solver, ux, vy, eff)
Unlike the dea function, this function expects input and output to be arrays or data.frames, not vectors.
Note: As this function is mainly for internal use, to avoid unnecessary overload, it does not do an extensive check of the input parameters. Use the higher level dea function instead.
