volcano_rnaseq_shiny_example

An example using R shiny to create a web app that generates volcano plots.

This basic app allows you to load a results table from DESeq2 and generate a volcano plot with reactive p-value and fold change thresholds.

You can access the test dataset in the "example_data" directory.

How to Run

The best way to start the app is to use renv.

1. Make sure you have R installed, > 4.3 should work.
2. Clone the repository to your local with git clone.
3. Enter the local directory with the repository and start the R interpreter.
4. Install all dependencies with renv::restore().
5. Start the app with shiny::runApp("shiny").
