input_coefficient_matrix_create {iotables} | R Documentation |
Create an input coefficient matrix
Description
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.
Usage
input_coefficient_matrix_create(data_table, households = FALSE, digits = NULL)
Arguments
data_table |
A symmetric input-output table, a use table,
a margins or tax table retrieved by the |
households |
Defaults to |
digits |
An integer showing the precision of the technology matrix in
digits. Default is |
Details
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
.
Value
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.
Examples
input_coefficient_matrix_create (
iotable_get(),
digits = 4 )
#This is a wrapper function and equivalent to
coefficient_matrix_create( iotable_get(),
total = "total",
return = "products")
