Link to source file

Warmup

Break off into pairs and introduce each other. Questions:

1. Year?
2. Major?
3. One type of data interested in studying?
   • (examples: simple numeric, text, time series, geospatial, network, survival, audio/video, other data specific to a subject area, etc…)
4. Some other fun/cool fact about you?

Setup R/Rstudio

Note: Chromebooks do not support R/Rstudio and thus are not sufficient for this class. Please talk to instructors/TAs if you are unable to find a suitable computer to use for this course.

• Install R
  • If you already have R, please check it’s the most recent version (4.0.3)

# show R version string
sessionInfo()$R.version$version.string

 # [1] "R version 4.0.3 (2020-10-10)"

• Install Rstudio

Setup course folder

It’s important to keep your course files organized. We recommend you organize your files in a folder structure like this:

• STAT340
  • lecture
  • discussion
    • 01
    • 02
    • …
  • homework
    • 01
    • 02
    • …
  • project
    • data
    • analysis
    • plots
    • …
  • …

Take a minute now to make the above. You can place STAT340 anywhere you like (e.g. Documents, Desktop, Dropbox, etc). Also move this file (ds01.Rmd) into STAT340/discussion/01 . After knitting, the next line should show your STAT340 directory structure correctly.

fs::dir_tree("../../../STAT340")

../../../STAT340
+-- discussion
|   +-- 01
|   |   +-- ds01.html
|   |   \-- ds01.Rmd
|   \-- 02
+-- homework
|   +-- 01
|   \-- 02
+-- lecture
\-- project
    +-- analysis
    +-- data
    \-- plots

Rstudio intro/refresher

• Panels (source, console, environment/history, plots/help/viewer)
• File operations (new, open, save, source, knit, etc.)
• Working directory
• Common shortcuts (run line, comment, insert chunk, etc.)

Final check

Make sure your R and Rstudio are both installed, up to date, and ready to rock. If you’re having issues, ask now!

Optional: backup/version control

It is strongly recommended you use some kind of backup or version control system (GitHub/Lab, Dropbox, Onedrive, etc.) so you don’t lose your course files if something unexpected happens. If you need help with this, please ask your instructors/TA.
