How to create an analysis environment

In this section, we will show an example of how to use this system for a class using "Rで学ぶデータサイエンス 14 計量政治分析』(Kyoritsu Shuppan) " as the textbook.

1. Create a repository on GitHub for the class, and place the environment configuration information (see below), programs and data files (if any) that will be used as teaching materials.
   
   • In this example, we will use

1. • https://github.com/ikfj/ds-polimetrics

1. • as the repository for the class.
   • In this repository, apt.txt

1. • and environment.yml

1. • are the environment configuration information and prepare.r

1. • is the teaching program.

   • Depending on the repository you are actually using, you may need to change the following description.

2. Open https://binder.cs.rcos.nii.ac.jp/

1.  in your browser.

5. Give the URL copied in Step 4 to the student.

The environment configuration information to be created in Step 1 is a text file describing the packages to be installed in the analysis environment. apt.txt describes the OS (Ubuntu) package, environment.yml describes the conda package, and so on. For more information on how to install other packages, please refer to https://mybinder.readthedocs.io/en/latest/using/config_files.html

or contact the person below.

6. Follow the instructor's instructions to use RStudio.

Note that a new analysis environment is created each time the URL is opened in step 1. This means that if you open this URL twice, the learner will have two analysis environments. A student can have up to 20 analysis environments.

When you are finished, save the modified file and close the browser. The analysis environment will not be lost when you close the browser.

To resume work in your own analysis environment that you created earlier

1. Open

1. https://jupyter.cs.rcos.nii.ac.jp/

1. in your browser.
