This chapter will introduce you to how to summarize data using R, as well as providing an introduction to a popular set of R tools known as the “Tidyverse.”
Before doing anything else we need to load the libraries that we will use in this notebook.
library(tidyverse)
library(cowplot)
library(knitr)
set.seed(123456)
opts_chunk$set(tidy.opts=list(width.cutoff=80))
options(tibble.width = 60)We will use the NHANES dataset for several of our examples, so let’s load the library that contains the data.
# load the NHANES data library
# first unload it if it's already loaded, to make sure
# we have a clean version
if("NHANES" %in% (.packages())){
detach('package:NHANES', unload=TRUE)
}
library(NHANES)
