Normalize values by reference range

Computes (value - lower) / (upper - lower). Values in the normal range fall between 0 and 1; below-range values are negative, above-range are > 1. Returns NA where the range is invalid (non-positive width or missing bounds).

Usage

normalize_by_range(value, lower, upper)

Arguments

value

Numeric vector of observed values.

lower

Numeric vector of lower reference bounds.

upper

Numeric vector of upper reference bounds.

Value

Numeric vector, same length as value.
