# ideal_weight_Traub: ideal weight for child per Traub In physiology: Calculate physiologic characteristics of awake and anesthetized adults, children and infants

## Description

`2.396e0.01863(height)`, where height is in cm. There is an argument for using another package to capture durations, of which age is a special case. However, I am resisting bringing in external dependencies, and for almost all use-cases I can imagine, the age will be captured as a single number of one type, not a mix of types. Note that gender does not appear to be important in this relationship.

See package AGD for CDC growth chart data.

## Usage

 `1` ```ideal_weight_Traub(height_m, age_y = NULL, ...) ```

## Arguments

 `height_m` single numeric, height in meters `age_y` numeric vector, age(s) in years. Extremely exact age is not required, so for age in days or months, simplest just to divide. This is not used in the calculation itself, so may be missing. `...` arguments passed to downstream functions, e.g. `warn = TRUE`

## Examples

 ```1 2 3 4 5 6 7 8 9``` ```# will warn if given age is not in validate range from publication: ## Not run: ideal_weight_child(height_m = 0.5, age_y = 0, do_warn = TRUE) ideal_weight_child(0.8, age_y = 11 / 12, do_warn = TRUE) ideal_weight_child(0.5, age_y = 25/365, do_warn = TRUE) ## End(Not run) ideal_weight_child(0.5, age_y = 25 / 365, do_warn = FALSE) ideal_weight_child(1, age_y = 2) ```
