Expansion means here that the dimensions of x are expanded acordingly 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)
# NOT RUN { a <- new.magpie(c("AFR","CPA"),"y1995",c("m","n"))
b <- new.magpie("GLO","y1995",c("bla","blub"))
magpie_expand(b,a)
options(magclass.verbosity=1)
magpie_expand(b,a)
# }
