    First we load the necessary libraries and set up the NHANES adult dataset

    library(tidyverse)
library(ggplot2)
library(knitr)
library(cowplot)

set.seed(123456)
opts_chunk$set(tidy.opts=list(width.cutoff=80))
options(tibble.width = 60)


# load the NHANES data library
library(NHANES)

# create a NHANES dataset without duplicated IDs 
NHANES <-
  NHANES %>%
  distinct(ID, .keep_all = TRUE) 

#create a dataset of only adults
NHANES_adult <- 
  NHANES %>%
  filter( 
    Age >= 18
  ) %>%
  drop_na(Height)
