[Blog?] Add notes on Quarto dashboard

[StatsRhian]

From C&C 2024-03

Why do I like dashboards

• Easy to create
• Shareable without a server

I used to train public health analysts
They did great work and wanted to share it with people
Blockers were

• time to learn shiny
• infrastructure for hosting
• data privacy issues

Why do I like Quarto?

• Working together
• Readable
• Mulit-language

Quarto dashboards

• Interactive, language agnostic dashboard
• Replaces {flexdashboard} for R Markdown
• Also works with {shiny}

Dashboards were release in Quarto v1.4

Who cares about Shiny?

• Complex to learn
• • Difficult to debug
• Have to have a server to deploy
• A bugger to deploy

Main components

• Cards

  • Plots
  • Tables
  • Text
  • Value boxes

• Structure

  • Rows
  • Columns
  • Sidebars

• Layout

  • Pages
  • Navbar

• One card,
• Another card
• Add titles on the cards (#| title:)
• Arrange with headings (dashboard: orientation:)
• Make a row with Head ## Row then column with ### Column
• {.tabset}
• Page
• row and heigh width / height
• Code cells automatically make cards
• sidebars can be within a page or global
• nav-buttons: github / twitter

Shiny isn't always the answer

• Shiny vs Static Quarto

• Hosting: Must be hosted with a live R server (or shinylive) - Just a HTML file - can send to anyone :D

• Skill level: Little harder - Low barrier to entry

• Requires a live connection

Deployment

• Static HTML website (rendered once)
• Schdeduled (Cron job)
• Parameterised (Connect)
• Fully interactive (SHINY)

What's in a widget?

• HTML widgets are simply

• {leaflet}

• {plotly}

• {DT}

• animation / plotly?

# Example leaflet map

You can even make your own

Other neat things

• You can turn ipynb into a dashboard
• Parameterisation

How interactive?

• Static one-off
• Regular automated reports
• Parameterisation
• Shiny

TLDR;

• Quarto dashboards are
• You can share and automate
