renderPlot

renderPlot(expr, width = "auto", height = "auto", res = 72, ...,
  env = parent.frame(), quoted = FALSE, func = NULL)

expr	An expression that generates a plot.
width,height	The width/height of the rendered plot, in pixels; or `'auto'` to use the `offsetWidth`/`offsetHeight` of the HTML element that is bound to this plot. You can also pass in a function that returns the width/height in pixels or `'auto'`; in the body of the function you may reference reactive values and functions. When rendering an inline plot, you must provide numeric values (in pixels) to both `width` and `height`.
res	Resolution of resulting plot, in pixels per inch. This value is passed to `png`. Note that this affects the resolution of PNG rendering in R; it won't change the actual ppi of the browser.
...	Arguments to be passed through to `png`. These can be used to set the width, height, background color, etc.
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.
func	A function that generates a plot (deprecated; use `expr` instead).

Renders a reactive plot that is suitable for assigning to an output slot.

The corresponding HTML output tag should be div or img and have the CSS class name shiny-plot-output.
