[R for R] R Data Visualization

At the time of video shooting, the default encoding of R was CP949 (EUC-KR) based on the Windows operating system, but it was later changed to UTF-8 encoding, which caused inconvenience in reading the file. More precisely, it was confirmed that the read.csv() function was not reading the "Seoul_COVID19_20210511.csv" file correctly.

So, to make it easier for you to practice, I have newly processed and added the "Seoul_COVID19_20210511_2.csv" file. Of course, you can also use the "Seoul City COVID-19 Confirmed Cases Status.csv" file instead of the file.

The newly uploaded data can be downloaded as a compressed file from the first class video, and the name of the compressed file is "ppt_data_scripts_ v20240202.zip ".

Thanks to magnet0922 for reporting this.

Hello, this is Seungwook Kim.

While updating our recent data, we noticed that the country_vaccinations.csv file was updated to the wrong version.

So I updated the entire zip file again and uploaded it.

If you re-download the files in the first lecture and run the code, you will get the desired result.

thank you
