Complete the following exercises in a new R script you create in R studio

A. Loading new packages

Write a script with your name and date at the top. Now write some code that first clears your working directory, and then loads the dplyr package. Note: if you have not successfully installed the dplyr package yet from CRAN, you will have to do that first.

B. Explore the new package

Open the dplyr vignette using the vignette() function. Scroll through the vignette. What is your favorite tool in dplyr? Write a brief description of it, in your own words, in a comment

C. Wrangle some data!

Using the iris dataset and dplyr functions, write code that (1) creates a new column, called area, that is the petal length times the petal width, and (2) calculate the maximum petal area of each species.
