create and download a GIF animation in Shiny

readme.md

You may have to install the development version of the animation package from Github: https://github.com/yihui/animation#readme

server.R

library(animation)
stopifnot(packageVersion('animation') >= '2.2.3')

shinyServer(function(input, output) {
  output$testgif = downloadHandler(
    filename = 'random.gif',
    content  = function(file) {
      saveGIF(
        for (i in 1:30) {
          plot(rnorm(100))
        }, movie.name = 'random.gif', interval = 0.1)
      file.rename('random.gif', file)
    })
})

ui.R

library(shiny)
shinyUI(basicPage(
  downloadButton("testgif")
))

I have the same issue as kmezhoud.
