Cumulative Distribution Plots for Pediatric Growth Standards

Cumulative Distribution Plots for Pediatric Growth Standards

Usage

gs_cdf(
  metric,
  male,
  age,
  height,
  length,
  source = getOption("pedbp_pgs_source", "CDC")
)

Arguments

metric

a character string denoting which growth metric to plot

male

integer value, 1 = male, 0 = female

age

numeric age, in months

length, height

in centimeters

source

a character string denoting the data source providing the parameters needed for the estimate. Valid values are "CDC" and "WHO". This can be set explicitly, or by using the pedbp_pgs_source option.

Value

a ggplot object
