  Theme lecture

  Week's ppt
  

  
  

  Hands-on exercise

  For the hands-on exercise, we will provide you with a new demo script. In the beginning of the hands-on session, we will fetch the demo script together. However, you can pull the demo script (demo3_food_production.rmd) already before the session and browse it through if you like (this is voluntary). If you'd like to watch a recap on how a git pull is performed, see the first workshop recording below.

  First week workshop recording

  We will go through the demo script step by step during the hands-on sessions. Again, the demo script contains few tasks marked with # TODO, which you can try filling in. We will provide model answers to all tasks after the demo session in another script.

  In addition to the domestic food production data introduced in the demo, we provide you with additional datasets on food supply and the prevalence of different BMI classes. See more in the Supporting materials (R and Data) tab.

  Written instructions on how to update course material are given below.

  1. Open your project from the wpcourse2022.Rproj file
  2. In RStudio, select Tools -> Shell
     
     
     
  3. Verify that the shell is in the wpcourse2022 folder. In Aalto VDI, the current directory of the shell is highlighted in yellow. If there's a cyan (main) tag after the path, the shell is in the correct directory. Changing directories can be done with the command cd path/to/directory.
     
     
     
  4. Commit any previous work according to the instructions in this video (note that the video is from 2021). The working tree should be clean as shown below. The output before the working tree can be "Your branch is XXX commits ahead of 'origin/master'" but that is expected and nothing special needs to be done for it.
     
     
     
  5. Type git pull into the shell and press enter.
  6. The shell pulls the changes from the version control system to your folder wpcourse2022.
  7. If you pull again, you should get "Already up to date." which means that you're good to go.
