Run a tutorial

Run a tutorial provided by an installed R package.

run_tutorial(
  name = NULL,
  package = NULL,
  ...,
  shiny_args = NULL,
  clean = FALSE,
  as_rstudio_job = NULL
)

Arguments

name

Tutorial name (subdirectory within tutorials/ directory of installed package). Alternatively, if package is not provided, name may be a path to a local tutorial R Markdown file or a local directory containing a learnr tutorial. If package is provided, name must be the tutorial name.

package

Name of package. If name is a path to the local directory containing a learnr tutorial, then package should not be provided.

...

Unused. Included for future expansion and to ensure named arguments are used.

shiny_args

Additional arguments to forward to shiny::runApp.

clean

When TRUE, the shiny prerendered HTML files are removed and the tutorial is re-rendered prior to starting the tutorial.

as_rstudio_job

Runs the tutorial in the background as an RStudio job. This is the default behavior when run_tutorial() detects that RStudio is available and can run jobs. Set to FALSE to disable and to run the tutorial in the current R session.

When running as an RStudio job, run_tutorial() sets or overrides the launch.browser option for shiny_args. You can instead use the shiny.launch.browser global option in your current R session to set the default behavior when the tutorial is run. See the shiny options documentation for more information.

Value

Starts a Shiny server running the learnr tutorial.
