Colorband Combination Generator

An R Shiny Electron desktop app

Users are able to generate all possible 4-band combinations using only their available color bands.

Completed March 11, 2020

Setup

You have three avenues of running this app:

1. Run online: https://lawaltr.shinyapps.io/colorband/
2. Run in R: shiny::runApp('colorband/shiny/app.R')
3. Package and run as a macOS Electron desktop app:
   • Make sure you have all dependencies installed (described in my setup guide)
   • In the R terminal, run cd colorband
   • Then run npm install
   • Run electron-forge start to see if the app works
   • And finally, run electron-forge make to package the app, now available to you in the out/ folder

Using the generator

1. Select the colorbands available at your banding station
2. If desired, choose your location from the drop-down
3. Save settings by clicking "Save choices"
   • Your selected colors and location will be remembered if the Shiny app is reloaded or refreshed
   • Note: This doesn't seem to work with the Electron desktop app yet
4. A random band combination will appear in the main panel
   • To generate a new random combination, hit the refresh button
5. To download a complete list of all possible combinations, click the "Download full .csv" button
