A Shiny app exploring Polar Bear population dynamics under different climate change scenarios

Two-file app using lterdatasampler & palmerpenguins data

This is the second app we'll build together during EDS 430. Instruction begins on this slide.

We'll cover the following:

• organizing code using a two file system (ui.R & server.R) + global.R
• using layout functions for customizing the visual structure of app UIs
• creating multiple inputs that control the same output
• importing styled text using includeMarkdown()
• publishing (& republishing) apps using shinyapps.io
• providing users helpful error messages using validate()
• adding loading animations to rendering outputs
• adding alt text to plots

We'll introduce the following packages:

• {shinyWidgets}
• {shinycssloaders}
• {lterdatasampler}
