runUrl: Run a Shiny application from a URL
In ymd526442121/Rproject_shiny: Web Application Framework for R

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, ...)

`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"`.
