Can I run all my software on my own computer?

Yes, you can! But you will need to install a specific version of R and Positron for everything to work as expected, along with the required R packages. You will also need to install Git, which is used for version control.

These are not extremely challenging things to get right, but they are not trivial either, particularly on certain operating systems. Myself and the TAs are always happy to provide help with any computational questions when you’re working in Posit Workbench. Since we have provisioned that server, we know it will work for all the assignments.1 If you’re working on your local setup, we can’t guarantee being able to resolve your issues, though we’re happy to try.

And I’d like to reiterate again that successful installation of these software is not a learning goal of this course. So if any of this seems tedious or intimidating in any way, just use the computing environment we have set up for you.

How do I export my assignment PDF from Posit Workbench to upload to Gradescope?

Note

This is only necessary if you are using Posit Workbench for the course. If you have installed R and Positron locally, you can skip this section.

  3. Right-click on the PDF file you want to download.
  4. Select Download from the context menu.

RStudio IDE

  3. Click the Download button. If you have selected multiple files to export, RStudio will zip them up into a single zip file for you. If you’ve selected just a single file, it will only download that. For assignments submitted via Gradescope, you only need to download the PDF. The downloaded file will go to wherever files you download off the internet goes on your computer (usually your Downloads folder).

How can I submit my assignment to Gradescope?

The instructions for submitting your assignment to Gradescope can be found here. In a nutshell, you’ll upload your PDF and them mark the page(s) where each question can be found. It’s OK if a question spans multiple pages, just mark them all. It’s also OK if a page includes multiple questions.
