Introduction
This is an adapted dashboard for COVID-19 visualization for Kenya. It is intended mainly for educational purposes especially students interested in R and data science. Due to different testing methods among countries, there is some uncertainity on the number of cases reported here in comparison to other sources.

The Coronavirus Dashboard: the case of Kenya
This Coronavirus dashboard: the case of Kenya provides an overview of the 2019 Novel Coronavirus COVID-19 (2019-nCoV) epidemic for Kenya. This dashboard is built with R using the R Makrdown framework and was adapted from this dashboard by Rami Krispin.
Code
The code behind this dashboard is available on GitHub.
Data
The input data for this dashboard is the dataset available from the {coronavirus} R package. Make sure to download the development version of the package to have the latest data:
install.packages("devtools")
devtools::install_github("RamiKrispin/coronavirus")

The data and dashboard are refreshed on a daily basis.
The raw data is pulled from the Johns Hopkins University Center for Systems Science and Engineering (JHU CCSE) Coronavirus repository.
Update
The data is as of Saturday May 23, 2020 and the dashboard has been updated on Sunday May 24, 2020.
