To load the iris dataset into R$,$ you will want to write the following command:

library$($datasets$)$

data$($iris$)$

Create a new R markdown document.

Add a title to the document, along with your name.

Add a level $1$ header that provides a name for the iris analysis.

Add a code chunk that assigns the iris dataset to a new variable $($iris is

included in the $R$ environment$).$ Make sure this code chunk is visible in

the document.

Add a level $2$ header that states 'Average Sepal Length by species'

Using dplyr$,$ group the dataset by species, and provide the average

sepal length. Include the code and the results in the document.

Add a code chunk that calls ggplot$2$ library, but do not include it in

your presentation.

Add a level $2$ header that states Visualizations'

Using a combination of histograms and box plots, visualize the

differences in sepal length, sepal width, petal length, and petal width

between the species, Set your code to be displayed in the document.

Under the visualizations, write a brief paragraph describing the

differences between the species.
