CovidYe

CovidYe package is created by Chengzhi Ye, which is followed strictly by the package-instructions. It contains one Shiny App, one data set and three functions. The main purpose of CovidYe package is to provide the basic information about COVID-19 of the countries with most confirmed cases and some functions to create the interactive plots and tables which are contains in the Shiny App.

Installation & Implementation

The development version can be installed from my GitHub with:

# install.packages("devtools")
devtools::install_github("etc5523-2020/r-package-assessment-Year-97")

After installing CovidYe package, you can type launch_app() in the console to run the Covid-19 Shiny App.

Example

A simple presentation of coronavirus data set:

library(CovidYe)
library(tibble)
library(dplyr)
library(tidyr)
library(plotly)
library(ggplot2)

as_tibble(coronavirus)

The Daily Situation and Cumulative Cases

coronavirus %>% 
  select(date, country, type, cases) %>% 
  group_by(type, date) %>%
  summarise(total_cases = sum(cases)) %>%
  pivot_wider(names_from = type, values_from = total_cases) %>%
  arrange(date) %>%
  mutate(totalconfirmed = cumsum(confirmed),
         totalrecovered = cumsum(recovered),
         totaldeath = cumsum(death)) %>% 
  head(10) %>% 
  kableExtra::kable()

The overall change trend of COVID-19

coronavirus %>% 
   select(date, country, type, cases) %>% 
  filter(country %in% c("US", "India", "Brazil", "Russia", "Peru")) %>% 
  filter(type == "confirmed") %>% 
  ggplot(aes(x = date, y = cases, color = country, lable = country)) +

  geom_line() +
  theme_bw()
