`R/iotables.R`

`iotables.Rd`

Pre-processing and basic analytical tasks related to working with Eurostat's symmetric input-output tables and provide basic input-output economics calculations. The package is a part of rOpenGov <http://ropengov.github.io/> for open source open government initiatives.

The iotables import function help downloading and pre-processing the Eurostat symmetric input-output tables and related tables.

`iotable_get`

returns a single table.

`employment_get`

downloads the employment data and processes
it to a conforming form.

These are various helper functions for accessing parts of the symmetric
input-output tables and joining them correctly.
`conforming_vector_create`

is a helper function taht creates
a named vector that conforms with the analytical objects, such as the
use table, the Leontieff-matrix, etc.

`household_column_get`

returns the final household
expenditure.

`primary_input_get`

will retrieve any primary input from
the input-output table. `output_get`

is a wrapper function around the
`primary_input_get`

function.

`total_tax_add`

adds taxes to an input-output table.

`input_flow_get`

returns the use (input flow) matrix.

`leontieff_matrix_create`

and the
`leontieff_inverse_create`

to create the respective analytical
matrixes.

`input_indicator_create`

The function creates the input indicators from the inputs and
the outputs.

`direct_effects_create`

for direct effects.

`coefficient_matrix_create`

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 the data table.

`multiplier_create`

is a wrapper around `equation_solve`

to create multipliers. This is a more generic helper function to calculate
various multipliers.

`input_multipliers_create`

is a function to create input
multipliers (for direct and indirect economic effects.)

`backward_linkages`

creates the vector of industry
(product) backward linkages in a wide
data.frame class, following the column names of the Leontieff
inverse matrix.

`forward_linkages`

creates 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`

.

Data files that contain descriptive metadata for a correct reproduction of the symmetric input-output tables. The analytical functions use matrix equations that require a precise column and row order for each table.

Data files that replicate published input-output tables with analysis. These files are used to validate the correct working of the analytical functions.

These are Croatia's symmetric input-output tables for the year 2010, when the country was not yet an EU member state.
