mappingToLongFormat

Derives a report aggregation mapping (sourceRegion to targetRegion) from a country-level region mapping. The input must have at least the columns countryname, country, and region. Any additional columns are treated as definitions of aggregated macro regions: each unique non-empty value defines a target region, and all source regions containing at least one country assigned to that value are mapped to it.

The output mapping has three blocks (each sorted by sourceRegion):

1. each source region mapped to itself (regional resolution)

2. each source region mapped to "GLO" (global aggregate)

3. source regions mapped to every additional aggregated region they belong to

Usage

mappingToLongFormat(mappingOrFileName)

Arguments

mappingOrFileName

Either a data frame containing the country-level region mapping, or a character string giving the path to a CSV-file.

Value

A data frame with columns sourceRegion and targetRegion.

Note

This function is a workaround as in magpie4 we can not use the same mapping formulas that we could use in madrat functions. If the magpie4 aggregation logic is ever rewritten, this function may become obsolete.
