For the given input and output build the lp_solve problem and return it.

lp_solve_dea(input, output, orientation = c("input", "output"), solve = FALSE)

Arguments

• 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".
