iotables (version 0.3.4)

forward_linkages: Forward linkages

Description

Forward linkages as defined by the Eurostat Manual of Supply, Use and Input-Output Tables (see p506-507.)

Usage

forward_linkages(output_coefficient_matrix, digits = NULL)

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.

Examples

# NOT RUN {
#You need a table that has a total column and either the total 
#intermediate use or final use
#This is usually the case with Eurostat tables, but with the Germany data
#file total must be added.

io_table <- iotable_get () 
io_table <- io_table [1:which(tolower(io_table[,1]) =="total" ), ]
output_bp <- dplyr::select ( io_table, output_bp )
io_table <- io_table [, 1:7] 
io_table$total <- rowSums(io_table[, 2:7])
io_table <- cbind (io_table, output_bp)

de_out_coeff <- output_coefficient_matrix_create ( io_table = io_table, 
                                    type = 'final_demand',
                                    digits = 4)

forward_linkages ( output_coefficient_matrix = de_out_coeff, 
                   digits = 4 )
