input_coefficient_matrix_create | R Documentation |
Create an input coefficient matrix from the input flow matrix and the output vector. The two input vectors must have consistent labelling, i.e the same column names must be found in the use table (input flow) and the output vector.
input_coefficient_matrix_create(data_table, households = FALSE, digits = NULL)
data_table |
A symmetric input-output table, a use table,
a margins or tax table retrieved by the |

An integer showing the precision of the technology matrix in
digits. Default is |
The input coefficients of production activities may be interpreted as the corresponding
cost shares for products and primary inputs in total output. Our terminology follows the
Eurostat Manual of Supply, Use and Input-Output Tables.

this matrix is called 'technological coefficients'. The results of the function are
tested on both sources. This is a wrapper function around coefficient_matrix_create
.
A data frame that contains the matrix of first quadrant of the use table as
input_flow
divided by output
supported by a key column of
product or industries, with a key column.
Optionally the results are rounded to given digits
.
An input coefficient matrix of data.frame class. The column names are ordered, and the row names are in the first, auxiliary metadata column.
