7.1 Load packages and import data
Let’s load some packages first:
library(tidyverse)
library(palmerpenguins)
library(skimr)
library(knitr)
library(janitor)
And we’re introducing a new package called naniar
, which helps us deal more easily with missing values in datasets.
You may need to install that package (recall you only do this once!). Consult a previous tutorial if you forget how.
Once you’ve installed it, load it:
library(naniar)
We will use the following datasets in this tutorial:
- the
birds.csv
file contains counts of different categories of bird observed at a marsh habitat - the
penguins
dataset that is available as part of thepalmerpenguins
package
<- read_csv("https://raw.githubusercontent.com/ubco-biology/BIOL202/main/data/birds.csv") birds
