In CrescNet/GrowthSDS: Utility Functions for Growth SDS Calculations

Description

Calculate SDS values. You can transform the resulting SDS values to a p-value by calling pnorm(). If you provide SDS values, y values will be returned instead.

Usage

sds(
  x,
  y,
  sex = "male",
  measurement = "height",
  ref = GrowthSDS::kromeyerHauschild,
  refName,
  recodeSex
)

Arguments

x	x value of the subject (e.g. (gestational) age)
y	y value of the subject (e.g. height)
sex	sex of the subject
measurement	measurement from which y originates
ref	Reference object to be used to calculate the SDS, defaults to kromeyerHauschild either ref or refName must be given
refName	name of the reference to be used to calculate the SDS values
recodeSex	list containing a mapping for sex to available sexes of the reference

Value

SDS value

Examples

sds(
  x   = 0,
  y   = 47,
  sex = 1,
  measurement = 'height',
  recodeSex   = list(`1` = 'male', `2` = 'female')
)
