htmlwidgets-shiny: Shiny bindings for HTML widgets
In DnPeter/htmlwidgets: HTML Widgets for R

Description Usage Arguments Details Value Examples

Helpers to create output and render functions for using HTML widgets within Shiny applications and interactive Rmd documents.

shinyWidgetOutput(outputId, name, width, height, package = name,
  inline = FALSE)

shinyRenderWidget(expr, outputFunction, env, quoted)

`outputId`	output variable to read from
`name`	Name of widget to create output binding for
`width, height`	Must be a valid CSS unit (like `"100%"`, `"400px"`, `"auto"`) or a number, which will be coerced to a string and have `"px"` appended.
`package`	Package containing widget (defaults to `name`)
`inline`	use an inline (`span()`) or block container (`div()`) for the output
`expr`	An expression that generates an HTML widget
`outputFunction`	Shiny output function corresponding to this render function.
`env`	The environment in which to evaluate `expr`.
`quoted`	Is `expr` a quoted expression (with `quote()`)? This is useful if you want to save an expression in a variable.

These functions are delegated to from within your widgets own shiny output and render functions. The delegation is boilerplate and always works the same for all widgets (see example below).

An output or render function that enables the use of the widget within Shiny applications.

# shiny output binding for a widget named 'foo'
fooOutput <- function(outputId, width = "100%", height = "400px") {
  htmlwidgets::shinyWidgetOutput(outputId, "foo", width, height)
}

# shiny render function for a widget named 'foo'
renderFoo <- function(expr, env = parent.frame(), quoted = FALSE) {
  if (!quoted) { expr <- substitute(expr) } # force quoted
  htmlwidgets::shinyRenderWidget(expr, fooOutput, env, quoted = TRUE)
}
