The increased output of a sector indicates that additional amounts of products are available to be used as inputs by other sectors which can increase their production, which is captured in this indicator vector.

## Arguments

- output_coefficient_matrix
An output coefficient matrix created with the

`output_coefficient_matrix_create`

function.- digits
Number of decimals for rounding, defaults to

`NULL`

.

## Value

The vector of industry (product) forward linkages in a
long-form data.frame, containing the metadata column of the the row
names from the `output_coefficient_matrix`

.

## Details

Forward linkages as defined by the Eurostat Manual of Supply, Use and Input-Output Tables (pp. 506--507) and the United Nations Handbook on Supply and Use Tables and Input-Output Tables with Extensions and Applications p637.

## See also

Other linkage functions:
`backward_linkages()`

## Examples

```
data_table = iotable_get()
de_out <- output_coefficient_matrix_create (
data_table, "tfu", digits = 4
)
forward_linkages(output_coefficient_matrix = de_out,
digits = 4 )
