Run a Shiny application from a URL — runUrl

v1.7.1|Source: R/run-url.R

Description

runUrl() downloads and launches a Shiny application that is hosted at a downloadable URL. The Shiny application must be saved in a .zip, .tar, or .tar.gz file. The Shiny application files must be contained in the root directory or a subdirectory in the archive. For example, the files might be myapp/server.r and myapp/ui.r. The functions runGitHub() and runGist() are based on runUrl(), using URL's from GitHub (https://github.com) and GitHub gists (https://gist.github.com), respectively.

runUrl(url, filetype = NULL, subdir = NULL, destdir = NULL, ...)

runGist(gist, destdir = NULL, ...)

runGitHub(
  repo,
  username = getOption("github.user"),
  ref = "master",
  subdir = NULL,
  destdir = NULL,
  ...
)

Arguments

url: URL of the application.
filetype: The file type (".zip", ".tar", or ".tar.gz". Defaults to the file extension taken from the url.
subdir: A subdirectory in the repository that contains the app. By default, this function will run an app from the top level of the repo, but you can use a path such as "inst/shinyapp".
destdir: Directory to store the downloaded application files. If NULL (the default), the application files will be stored in a temporary directory and removed when the app exits
...: Other arguments to be passed to runApp(), such as port and launch.browser.
gist: The identifier of the gist. For example, if the gist is https://gist.github.com/jcheng5/3239667, then 3239667, '3239667', and 'https://gist.github.com/jcheng5/3239667' are all valid values.
repo: Name of the repository.
username: GitHub username. If repo is of the form "username/repo", username will be taken from repo.
ref: Desired git reference. Could be a commit, tag, or branch name. Defaults to "master".
