Unleash-Shiny 2021

R/Pharma workshop (2hours)

Setup

Clone this repository with the RStudio IDE or via the command line.

git clone https://github.com/RinteRface/unleash-shiny-2021.git
cd unleash-shiny-2021

Then run renv::restore() to install the dependencies.

⚠️ this workshop makes heavy use of npm (Node's Package Manager), it comes with the installation of node.js.

• You can manually install node.js: nodejs.org/en/download/
• You can also use package managers: nodejs.org/en/download/package-manager/

If you have restored the renv state and have nodejs installed run the line below to check whether it is ready for the workshop. It will print helpful messages if it is not.
