Tell whether industry inputs are unit-homogeneous and industry outputs are unit-homogeneous

Returns TRUE if each industry's inputs are unit-homogeneous and each industry's outputs are unit homogeneous. When inputs have different units from outputs, (but all inputs are unit-homogeneous and all outputs are unit-homogeneous), TRUE is returned.

Usage

inputs_outputs_unit_homogeneous(
  .sutmats = NULL,
  U = "U",
  V = "V",
  S_units = "S_units",
  keep_details = FALSE,
  ins_outs_unit_homogeneous = ".inputs_outputs_unit_homogeneous"
)

Arguments

.sutmats: a data frame of supply-use table matrices with matrices arranged in columns.
U: a use (U) matrix or name of the column in .sutmats that contains same. Default is "U".
V: a make (V) matrix or name of the column in .sutmats that contains same. Default is "V".
S_units: an S_units matrix or name of a column in .sutmats that contains same. Default is "S_units".
keep_details: if TRUE, per-industry results are returned; if FALSE, per-ECC results are returned.
ins_outs_unit_homogeneous: the name of the output column that tells whether each industry's inputs and outputs are unit-homogeneous (though not necessarily in the same units). Default is ".inputs_outputs_unit_homogeneous".

Value

a list or data frame containing TRUE if inputs from each energy conversion industry are unit-homogeneous and outputs from each energy conversion industry are unit-homogeneous, FALSE otherwise.

Details

This function uses both inputs_unit_homogeneous and outputs_unit_homogeneous internally. This function differs from flows_unit_homogeneous, because flows_unit_homogeneous requires that all flows are unit-homogeneous before returning TRUE. This function (inputs_outputs_unit_homogeneous) will return true when all inputs are unit-homogeneous with different units from outputs (which are also unit-homogeoenous).

Examples

library(tidyr)
result <- UKEnergy2000mats %>%
  spread(key = "matrix.name", value = "matrix") %>%
  inputs_outputs_unit_homogeneous()
