Title: Animate 'ggplot2' Plots with 'Anime.js'
Version: 0.1.0
Description: Renders 'ggplot2' plots written with 'gganimate' syntax as animated Scalable Vector Graphics (SVG) drawn in the browser by the 'Anime.js' JavaScript library (https://animejs.com), through the 'animejs' package. The result is a single self-contained, resolution-independent 'htmlwidget' with one timeline over the plot's elements.

Render a gganimate plot as an animated-SVG widget

Description

Builds a ggplot2 plot written with gganimate syntax and renders it as a self-contained, resolution-independent animated-SVG htmlwidget powered by Anime.js, instead of gganimate's frame-by-frame output.

Usage

anime(
  plot,
  nframes = 100,
  fps = 10,
  duration = NULL,
  width = 640,
  height = 480,
  precision = 2,
  loop = TRUE,
  controls = TRUE,
  elementId = NULL,
  ...
)

Arguments

plot

A gganim plot: a ggplot2 plot with a ⁠transition_*()⁠ added.

nframes

Number of frames to sample the animation at.

fps

Frames per second, setting the playback speed.

duration

Optional total duration in seconds; overrides fps.

width, height

Widget size in pixels, defaulting to 640 by 480. The plot is rendered at these dimensions, so their ratio sets the plot's aspect ratio.

precision

Decimal places to round animated coordinates to.

loop

Loop the animation: TRUE, FALSE, or a number of iterations.

controls

Show a play/pause and scrub control bar.

elementId

Optional htmlwidget element id.

...

Unused; reserved for future arguments.

Value

An htmlwidget of class gganime.

Examples

library(ggplot2)

p <- ggplot(iris, aes(Sepal.Width, Sepal.Length, size = Petal.Length)) +
  geom_point(colour = "steelblue") +
  labs(title = "{closest_state}") +
  transition_states(Species)


anime(p, nframes = 20)

Shiny bindings for gganime

Description

Output and render functions for using gganime widgets within Shiny applications and interactive R Markdown documents.

Usage

gganimeOutput(outputId, width = "100%", height = "400px")

renderGganime(expr, env = parent.frame(), quoted = FALSE)

Arguments

outputId

Output variable to read from.

width, height

Must be a valid CSS unit (like "100%", "400px", "auto") or a number, which will be coerced to a string and have "px" appended.

expr

An expression that generates a gganime widget, typically a call to anime().

env

The environment in which to evaluate expr.

quoted

Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable.

Value

gganimeOutput() returns a Shiny output function for a UI definition; renderGganime() returns a Shiny render function to assign to an output slot.

Examples

if (interactive() && rlang::is_installed("shiny")) {
  library(shiny)
  library(ggplot2)

  ui <- fluidPage(gganimeOutput("plot"))

  server <- function(input, output, session) {
    output$plot <- renderGganime({
      anime(
        ggplot(mtcars, aes(mpg, wt)) +
          geom_point() +
          transition_states(gear)
      )
    })
  }

  shinyApp(ui, server)
}
