## Make a copy of today's project

- Whenever you start any project for the first time, make a copy for yourself. Only make a copy the first time you work on a project. You can come back and your project will still be there for you to continue working on it.

- Once you make a copy, it may take time to deploy project. Give it some time. Refresh the page if needed.

- Once your project has loaded click on the .Rmd file on the lower right panel to open it. If you have completed these steps make sure that those around you have also completed them.

# What is R Markdown?

We will have a more sophisticated definition of R Markdown later but for now you can think of it as a file that can have R code and text.

R code files (i.e. R scprits) have .R extension.  
Markdown files which are text files in essence have .md extension.   
R Markdown files that have both R and md components have .Rmd extension.

For instance all of this presentation is written in R Markdown because I can write text and R code at the same time such as the one below

# Knitting

The way to "run" or "process" a R Markdown document is called _knitting_

Now that you have your .Rmd file open go ahead and Knit your document by

- Clicking the Knit button or

- Using short cut Ctrl (Cmd on Mac) + Shift + K

Saving documents - Every time you knit it saves

Note that you have different knit options such as knitting to HTML or pdf. We will use pdf because it is easier to upload to Gradescope.

## Getting Ready for Submission
