# 13: Sampling in R


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)
