Vectorized growth percentiles for infants and children (generic)

Description

Internal generic function to calculate weight/height/BMI growth percentiles for age/height for infants and children using CDC Growth Charts data and equations.

Usage

pct_growth_generic(
  x,
  y,
  sex,
  growth_chart,
  return_numeric = TRUE,
  return_median = FALSE,
  x_argname = "x",
  y_argname = "y",
  y_units = "raw"
)

Arguments

x	A numeric vector of weights/heights/BMIs.
y	A numeric vector of ages/heights in the unit specified in y_units.
sex	A character vector specifying patient sex. Either "male" or "female".
growth_chart	A CDC growth chart data frame (see growth-charts).
return_numeric	Return a numeric vector of percentiles for the given physical measurement? Defaults to TRUE. If FALSE, a data frame is returned with the observed percentile for the given physical measurement (P_obs), along with a select distribution of physical measurements at particular percentiles (P01 to P999; the 0.1st to 99.9th percentiles).
x_argname, y_argname	A character string for naming the x and y arguments in relevant output.

Value

When return_numeric = TRUE, a vector of percentiles for the given physical measurement; when return_numeric = FALSE, a growth chart data frame.
