Minmax a vector

Scales a vector using min-max method.

Usage

n_minmax(x, l_u = c(0, 100))

Arguments

x

A numeric vector

l_u

A vector c(l, u), where l is the lower bound and u is the upper bound. x will be scaled exactly onto this interval.

Value

Normalised vector

Details

This function also supports parameter specification in iMeta for the Normalise.coin() method. To do this, add columns minmax_lower, and minmax_upper to the iMeta table, which specify the lower and upper bounds to scale each indicator to. Then set f_n_para = "use_iMeta" within the global_specs list. See also examples in the normalisation vignette.

Examples

x <- runif(20)
