In ronkeizer/clinPK: Clinical Pharmacokinetics Toolkit

Description

Get an estimate of body-surface area based on weight, height, and sex (and age for Storset equation).

Usage

calc_ffm(weight = NULL, bmi = NULL, sex = NULL, height = NULL,
  age = NULL, method = "green", digits = 1)

Arguments

weight	total body weight in kg
bmi	BMI, only used in 'green' method. If 'weight' and 'height' are both specified, 'bmi' will be calculated on-the-fly.
sex	sex, either 'male' of 'female'
height	height in cm, only required for 'holford' method, can be used instead of 'bmi' for 'green' method
age	age, only used for Storset equation
method	estimation method, either 'green' (default), 'holford', or 'storset'
digits	round to number of digits
