Data & Computational Work

The main purpose of this week’s assignment is to get your computer ready for all the work in the class. This means, primarily, installing software.

Install R on your computer

Begin by installing R (http://cloud.r-project.org). Choose the version appropriate for your computing platform:

• If you use macOS with an Apple Silicon processor (i.e. an M-series processor), then install R for macOS’s Apple Silicon build. This version does not work on older, Intel-based Macs.

• If you use macOS with an Intel processor, then install R for macOS’s Intel build.

• If you use Microsoft Windows, then install R for Windows.

• If you use Linux, choose your distribution and install the R package for it.

Install RStudio on your computer

• If you use macOS (whether Apple Silicon or Intel), install this version of RStudio.

• If you use Windows, install this version of RStudio.

• If you use Linux, choose your distribution from the download page.

Confirm things work

• R is really a great big calculator. Let’s do some calculations!
  • Add 2 and 3 together
  • Multiply 4 by 6
  • Divide 10 by 5

Submit: .R File (Optional)

In an .R file, write code to answer the following questions. Make sure your file is appropriately titled and headered.

Note: You can submit this R file in Week 2, if you prefer.
