Scales a vector for normalisation using the method applied in the GII2020 for some indicators. This
does x_scaled <- (x-l)/(u-l) * scale_factor. Note this is not the minmax transformation (see n_minmax()).
This is a linear transformation with shift u and scaling factor u-l.
Optional scaling factor to apply to the result. Default 100.
Details
This function also supports parameter specification in iMeta for the Normalise.coin() method.
To do this, add columns scaled_lower, scaled_upper and scale_factor to the iMeta table, which specify the
first and second elements of npara, respectively. Then set f_n_para = "use_iMeta" within the
global_specs list. See also examples in the normalisation vignette.
