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.
