coefficient_matrix_create: Create a coefficient matrix

Description

Create a coefficient matrix from a Symmetric Input-Output Table. The coefficient matrix is related by default to output, but you can change this to total supply or other total aggregate if it exists in your table.#'

Usage

coefficient_matrix_create(
  data_table,
  total = "output",
  digits = NULL,
  remove_empty = TRUE,
  households = FALSE,
  return_part = NULL
)

Arguments

data_table

A symmetric input-output table, a use table, a margins or tax table retrieved by the iotable_get function.

total

Usually an output vector with a key column, defaults to "output" which equals "P1" or "output_bp". You can use other rows for comparison, for example "TS_BP" if it exists in the matrix.

digits

An integer showing the precision of the technology matrix in digits. Default is NULL when no rounding is applied.

remove_empty

Defaults to TRUE. If you want to keep empty primary input rows, choose FALSE. Empty product/industry rows are always removed to avoid division by zero error in the analytic functions.

households

Defaults to NULL. Household column can be added with TRUE.

return_part

Defaults to NULL. You can choose "product" or "industry" to return an input coefficient matrix or "primary_inputs" to get only the total intermediate use and proportional primary inputs.

Value

A data.frame that contains the matrix of data_table divided by total with a key column. Optionally the results are rounded to given digits.
