Pediatric Growth Standard Charts
Description
Growth standards based on data from the Centers for Disease Control and the World Health Organization.
Usage
gs_chart(
metric,
male = 0:1,
source = getOption("pedbp_pgs_source", "CDC"),
p = c(0.01, 0.05, 0.1, 0.25, 0.5, 0.75, 0.9, 0.95, 0.99)
)
Arguments
metric |
character string, one of the growth standards |
male |
integer value, 1 = male, 0 = female |
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 |
p |
a numeric vector of the probabilities, provided in values between 0 and 1, to plot |
Value
A ggplot
object
Notes
CDC Recommends using WHO growth charts for infants and children ages 0 to 2 years of age in the U.S. and CDC growth charts to monitor growth for children age 2 years and older in the U.S.
