Online Usage

The app is available online at stratigraphicpaleobiology.shinyapps.io/DarwinCAT
Online access works with a web browser and does not require any coding skills or installations.

Offline Usage

Running the app offline requires R version 3.3 or later, RStudio, and the R packages "renv", "shiny" and "png".

1. Open the R project: Go to File -> Open Project, then navigate to the DarwinCAT folder and open the DarwinCAT Rproject file (file ending .Rproj). This will bootstrap the renv package.

2. Run

   renv::restore()

   This will install all packages dependencies required to run the app.

3. Now you can start the app by running the command

   shiny::runApp()
