1. Difference between this repository and the origin one

Please read Readme.md

2. Download data without reading Vorwort session in Lerneinheit R - Arbeiten mit CSV-Dateien

Please click https://github.com/SchenbergZY/Tabelle-Fallstudie-1/raw/main/21341-0001_$F.csv to download the table to your computer. And then please upload the downloaded file to Binder or Colab you are running with.

3. User Experience of Lerneinheit R - Arbeiten mit CSV-Dateien

3.1 2 bugs which happen under Colab/Binder but not happen under Windows command line.

3.1.1 Function choose.files()

This function has no effect running under Colab/Binder when trigger. However in Windows command line, a window will pop out to let you choose a csv file to be loaded.

3.1.2 Function edit()

This function has no effect running under Colab/Binder when trigger. However in Windows command line, a window will pop out to let you edit the dataframe parameter on fly.

3.2 Using Experience under Colab

  1. User needs to upload the CSV file
  2. tidyverse pre-installed so just run installing takes a short time
  3. running cell head(data_csv) after dataframe loaded takes infinite time as some text in the origin CSV file is not UTF-8 encoded, and user has to stop running the cell. After that user need to rerun library(tidyverse) and data_csv read command again. Otherwise there will be other bugs in showing the dataframe loaded
  4. choose.files() not work in Colab
  5. running ?read.csv2 pop up a window at the right side of the webpage
  6. show(data_csv_3) not work because nothing called data_csv_3 defined
  7. pandoc pre-installed so just run installing takes a short time
  8. edit(Tabellendaten) not work in Colab

3.3 Using Experience under Binder

  1. User needs to upload the CSV file
  2. tidyverse not-installed so run installing takes a long time
  3. running cell head(data_csv) after dataframe loaded takes long time as some text in the origin CSV file is not UTF-8 encoded, please wait till finished.
  4. choose.files() not work in Binder
  5. running ?read.csv2 pop up a window at the right side of the webpage
  6. show(data_csv_3) not work because nothing called data_csv_3 defined
  7. pandoc not installed so run installing takes a while
  8. edit(Tabellendaten) not work in Binder

3.4 Using Experience under Live Code

Waiting for long time with no response.

4. User Experience of Reproduzierbarkeit Nationaler Bildungsbericht

  1. Convert back to the German-specific letter
  2. left-strip the space of column "Angestelltenverhaeltnis"
  3. Convert column "Personalgruppe" to "Arbeitsverhältnis"

5. User Experience of 3rd ipynb
