This is an R package that provides versioned time series data for COVID-19 from the JHU data repository at

Installation and Updating Data

For this package to be useful, you will need to clone it and install it from your local copy after you have updated the data.

To clone the repository, in a terminal you can run git clone

installation prerequisites

You will need R 3.x or 4.x

installation using make

We recommend using make to simplify the updating of data. However, some Windows operating systems do not allow for easy use of the command make, so manual installation should be used if make does not work.

To use make, you must complete the following steps once you have cloned the repository:

  1. In a terminal/shell window, navigate to code/data-processing.
  2. Run make all. (This runs the steps below.)

Note: If you want to only download the most recent JHU data files, for step 2. instead run make recent_data

manual installation

If make does not work for you, you may run the following steps by hand. To update the data, please:

  1. Clone the repository. If you have previously installed covidData from an existing local clone, pull any updates to the package by running git pull origin master from the terminal, with the repository folder as your working directory.
  2. Run R CMD INSTALL covidData from the terminal
