magclass (version 5.24.7)

magpie_expand: magpie_expand

Description

Expands a MAgPIE object based on a reference

Usage

magpie_expand(x, ref)

Arguments

x

MAgPIE object that should be expanded

ref

MAgPIE object that serves as a reference

Value

An expanded version of x.

Details

Expansion means here that the dimensions of x are expanded accordingly to ref. Please note that this is really only about expansion. In the case that one dimension of ref is smaller than of x nothing happens with this dimension. At the moment magpie_expand is only internally available in the magclass library

You can influence the verbosity of this function by setting the option "magclass.verbosity". By default verbosity is set to 2 which means that warnings as well as notes are returned. Setting verbosity to 1 means that only warnings are returned but no notes. This is done by options(verbosity.level=1)

With version 5 of the package magpie_expand has been updated to a newer version (currently 2.1). To switch to the old setup you have to set options(magclass_expand_version=1).

By default expansion is based on the elements in a dimension ignoring the set name of the dimension. To expand based on set names instead of contents (recommended) you can switch options(magclass_setMatching=TRUE). Please be careful with this setting as it alters the behavior of magclass objects quite significantly! For more information have a look at vignette("magclass-expansion").
