Start a Shiny server for the given document, and render it for display.
run(
file = "index.Rmd",
dir = dirname(file),
default_file = NULL,
auto_reload = TRUE,
shiny_args = NULL,
render_args = NULL
)
Path to the R Markdown document to launch in a web browser.
Defaults to index.Rmd
in the current working directory, but may be
NULL
to skip launching a browser.
The directory from which to to read input documents. Defaults to
the parent directory of file
.
The file to serve at the Shiny server's root URL. If
NULL
(the default), a sensible default is chosen (see Details)
If TRUE
(the default), automatically reload the
Shiny application when the file currently being viewed is changed on disk.
Additional arguments to runApp
.
Additional arguments to render
.
Invisible NULL.
The run
function runs a Shiny document by starting a Shiny
server associated with the document. The shiny_args
parameter can be
used to configure the server; see the runApp
documentation for details.
Once the server is started, the document will be rendered using
render
. The server will initiate a render of the document
whenever necessary, so it is not necessary to call run
every time
the document changes: if auto_reload
is TRUE
, saving the
document will trigger a render. You can also manually trigger a render by
reloading the document in a Web browser.
The server will render any R Markdown (.Rmd
) document in dir
;
the file
argument specifies only the initial document to be
rendered and viewed. You can therefore link to other documents in the
directory using standard Markdown syntax, e.g.
[Analysis Page 2](page2.Rmd)
.
If default_file
is not specified, nor is a file specified on the
URL, then the default document to serve at /
is chosen from (in
order of preference):
If dir
contains only one Rmd
, that Rmd
.
The file index.Rmd
, if it exists in dir
.
The first Rmd
that has runtime: shiny
in its YAML metadata.
The file index.html
(or index.htm
), if it exists in dir
.
If you wish to share R code between your documents, place it in a file
named global.R
in dir
; it will be sourced into the global
environment.
Unlike render
, run
does not render the document to
a file on disk. In most cases a Web browser will be started automatically
to view the document; see launch.browser
in the
runApp
documentation for details.
When using an external web browser with the server, specify the name of the
R Markdown file to view in the URL (e.g.
http://127.0.0.1:1234/foo.Rmd
). A URL without a filename will show
the default_file
as described above.
