Overview In this blog post I will be reviewing alangewerc’s R package covidshiny which is containing coronavirus data, functions, and shiny application. The development version from GitHub. The goal of CovidShiny is to present the user the evolution of the pandemic related to COVID-19 across the world.

section 1 :） introduce COVID19_tracker shiny app 1. here is my app link. https://chenjie-gong.shinyapps.io/covid19/ 2. why create it? The original intention of creating this app was to let people see the data of the epidemic more intuitively, rather than the news of COVID-19 all over the world, but they could not understand the epidemic situation in various places intuitively.

hi, this is my second blog, which is about the swiss. :D In the previous blog, I briefly introduced COVID. This blog is about Switzerland. The first part is why it is recommended to travel to Switzerland, and the second part is to analyze the epidemic situation in Switzerland.

hi i am chenjie :D 2020 is not a good period. People all over the world have been badly affected by this virus. For example, we cannot go back to school for offline courses.
