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.

## iotables import functions

iotable_get returns a single table.

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

## iotables processing functions

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.

## analytical object functions

input_flow_get returns the use (input flow) matrix.

leontieff_matrix_create and the leontieff_inverse_create to create the respective analytical matrixes.

## indicator functions

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 functions

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.
