If you use a Chromebook, or if you have another reason to run RStudio
online, you may wish to try https://rstudio.cloud, which allows you to
run RStudio in a web browser.

Click "New Project" the first time you enter. Then you should see the
same RStudio interface we use in class.

Here's one way to get the knitted ".html" file out of rstudio.cloud:
- click the Files tab
- check the box of the ".html" file
- click "More ..." (in the Files tab menu)
- choose Export
- click Download
