Quarto (Pre-release) – Quarto Presentations

Hello, There

This presentation will show you examples of what you can do with Quarto and Reveal.js, including:

Presenting code and LaTeX equations
Including computations in slide output
Image, video, and iframe backgrounds
Fancy transitions and animations
Activating scroll view

…and much more

Pretty Code

Over 20 syntax highlighting themes available
Default theme optimized for accessibility

# Define a server for the Shiny app
function(input, output) {
  
  # Fill in the spot we created for a plot
  output$phonePlot <- renderPlot({
    # Render a barplot
  })
}

Code Animations

Over 20 syntax highlighting themes available
Default theme optimized for accessibility

# Define a server for the Shiny app
function(input, output) {
  
  # Fill in the spot we created for a plot
  output$phonePlot <- renderPlot({
    # Render a barplot
    barplot(WorldPhones[,input$region]*1000, 
            main=input$region,
            ylab="Number of Telephones",
            xlab="Year")
  })
}

Line Highlighting

Highlight specific lines for emphasis
Incrementally highlight additional lines

import numpy as np
import matplotlib.pyplot as plt

r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()

Executable Code

library(ggplot2)
ggplot(mtcars, aes(hp, mpg, color = am)) +
  geom_point() +
  geom_smooth(formula = y ~ x, method = "loess")

LaTeX Equations

MathJax rendering of equations to HTML

\begin{gather*}
a_1=b_1+c_1\\
a_2=b_2+c_2-d_2+e_2
\end{gather*}

\begin{align}
a_{11}& =b_{11}&
  a_{12}& =b_{12}\\
a_{21}& =b_{21}&
  a_{22}& =b_{22}+c_{22}
\end{align}

\[\begin{gather*} a_1=b_1+c_1\\ a_2=b_2+c_2-d_2+e_2 \end{gather*}\] \[\begin{align} a_{11}& =b_{11}& a_{12}& =b_{12}\\ a_{21}& =b_{21}& a_{22}& =b_{22}+c_{22} \end{align}\]

Column Layout

Arrange content into columns of varying widths:

Motor Trend Car Road Tests

The data was extracted from the 1974 Motor Trend US magazine, and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles.

	mpg	cyl	disp	hp	wt
Mazda RX4	21.0	6	160	110	2.620
Mazda RX4 Wag	21.0	6	160	110	2.875
Datsun 710	22.8	4	108	93	2.320
Hornet 4 Drive	21.4	6	258	110	3.215
Hornet Sportabout	18.7	8	360	175	3.440
Valiant	18.1	6	225	105	3.460

Incremental Lists

Lists can optionally be displayed incrementally:

First item
Second item
Third item

Insert pauses to make other types of content display incrementally.

Fragments

Incremental text display and animation with fragments:

Fade in

Slide up while fading in

Slide left while fading in

Fade in then semi out

Strike

Highlight red

Slide Backgrounds

Set the background attribute on a slide to change the background color (all CSS color formats are supported).

Different background transitions are available via the background-transition option.

Media Backgrounds

You can also use the following as a slide background:

An image: background-image
A video: background-video
An iframe: background-iframe

Absolute Position

Position images or other elements at precise locations

Auto-Animate

Automatically animate matching elements across slides with Auto-Animate.

Auto-Animate

Automatically animate matching elements across slides with Auto-Animate.

Slide Transitions

The next few slides will transition using the slide transition

Transition	Description
`none`	No transition (default, switch instantly)
`fade`	Cross fade
`slide`	Slide horizontally
`convex`	Slide at a convex angle
`concave`	Slide at a concave angle
`zoom`	Scale the incoming slide so it grows in from the center of the screen.

Interactive Slides

Include Jupyter widgets and htmlwidgets in your presentations

Interactive Slides

Turn presentations into applications with Observable and Shiny. Use component layout to position inputs and outputs.

viewof talentWeight = Inputs.range([-2, 2], { value: 0.7, step: 0.01, label: "talent weight" })
viewof looksWeight = Inputs.range([-2, 2], { value: 0.7, step: 0.01, label: "looks weight" })
viewof minimum = Inputs.range([-2, 2], { value: 1, step: 0.01, label: "min fame" })

import { plotActors } from './actors.js';
plotActors(actors, talentWeight, looksWeight, minimum)

Preview Links

Navigate to hyperlinks without disrupting the flow of your presentation.

Use the preview-links option to open links in an iframe on top of your slides. Try clicking the link below for a demonstration:
