nCov2019: An R package with real-time data, historical data and Shiny app

Please visit https://github.com/YuLab-SMU/nCov2019 for an up-to-date version.

This package is one of the earliest R packages that designed to query COVID data. It is available since Jan. 2020, at the time there were few data resources available (see our blog post (in Chinese) (Feb. 03, 2020) and another blog post by third party (in English) (Feb. 11, 2020)).

🏠 Data Sources

Real-time data

• Tencent SARS-COV-2 website.

Historical data (three public data sources):

1. Wuhan-2019-nCoV GitHub repository.

   • This data source contains detailed city level data in China, and country level data in worldwide.

2. National Health Commission of the People’s Republic of China

   • This data source contains province level data in China.

3. DXY.cn. Pneumonia. 2020.

   • We collect historical city level data in China from this source.

4. 今日头条

   • We collect historical province level data for oversea countries form this source. (Start from 2020-03-15)

     The user can obtain the historical provincial data in China, South Korea, United States, Japan, Iran, Italy, Germany and United Kingdom now.

     For example, the below will return the historical data for Italy.

     library(nCov2019)
     nCov2019_set_country(country = 'Italy') 
     x['province'] # this will return Italy data only.
