Wrangle weight-for-height data

Source: R/wrangle-wfhz.R
mw_wrangle_wfhz.Rd

Calculate z-scores for weight-for-height (WFHZ) and identify outliers based on the SMART methodology.

Usage

mw_wrangle_wfhz(df, sex, weight, height, .recode_sex = TRUE, .decimals = 3)

Arguments

df

A data.frame object to wrangle data from.

sex

A numeric or character vector of child's sex. Code values should only be 1 or "m" for males and 2 or "f" for females.

weight

A vector of class double of child's weight in kilograms.

height

A vector of class double of child's height in centimetres.

.recode_sex

Logical. Set to TRUE if the values for sex are not coded as 1 (for males) or 2 (for females). Otherwise, set to FALSE (default).

.decimals

The number of decimal places to use for z-score outputs. Default is 3.

Value

A data frame based on df with new variables named wfhz for child's WFHZ and flag_wfhz for detected outliers added.
