inputs_unit_homogeneous: Tell whether each industry's inputs are unit-homogeneous

In MatthewHeun/Recca: R Energy Conversion Chain Analysis

Tell whether each industry's inputs are unit-homogeneous

Description

Returns TRUE if each industry's inputs are unit-homogeneous.

Usage

inputs_unit_homogeneous(
  .sutmats = NULL,
  U = "U",
  S_units = "S_units",
  keep_details = FALSE,
  ins_unit_homogeneous = ".inputs_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".
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-product results are returned; if FALSE, per-ECC results are returned. Default is FALSE.
ins_unit_homogeneous	name of the output boolean that tells whether each industry's inputs are unit-homogeneous. Default is ".inputs_unit_homogeneous".

Details

The U_bar matrix is queried for the number of non-zero entries in each column. If the number of non-zero entries in each column is exactly 1, industry inputs are unit-homogeneous. Note that U_bar = matrixproduct_byname(transpose_byname(S_units), U).

Value

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

Examples

library(tidyr)
UKEnergy2000mats %>%
  spread(key = "matrix.name", value = "matrix") %>%
  inputs_unit_homogeneous()
