Natural log transformation... providing breaks on the "nel" scale

Natural log transformation... providing breaks on the "nel" scale

Usage

nel_trans(n = 7, base = exp(1), use_centiNel = FALSE, ...)

Arguments

n

Scalar, target number of breaks

base

a positive or complex number: the base with respect to which logarithms are computed. Defaults to \(e\)=exp(1).

use_centiNel

Logical, should units be "centiNels" (default is "nel")

...

Additional arguments passed to breaking function, labeller
