Pre-processing and basic analytic 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.
import functions
The iotables import function help downloading and pre-processing the Eurostat symmetric input-output tables and related tables.
iotable_get returns a single table.
iotables_read_tempdir reads data from the temporary directory of a session.
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 that creates
a named vector that conforms with the analytical objects, such as the
use table, the Leontief-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.
empty_remove symmetrically removes columns and rows if they contain missing values,
or each and every value is zero.
rows_add Add conforming row(s) to a matrix.
key_column_create This function will likely be used with the creation of coefficients that need to be matched with
a matrix that has a key column.
analytic object functions
input_flow_get returns the use (input flow) matrix;
leontief_matrix_create and the
leontief_inverse_create to create the respective analytic
matrixes.
ghosh_inverse_create will create the Gosh-inverse.
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.)
linkage functions
backward_linkages creates the vector of industry
(product) backward linkages in a wide
data.frame class, following the column names of the Leontief
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.
Metadata datasets
Data files that contain descriptive metadata for a correct reproduction of the symmetric input-output tables. The analytic functions use matrix equations that require a precise column and row order for each table.
