##### Plot Output

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

##### Usage
renderPlot(expr, width = "auto", height = "auto", res = 72, ..., env = parent.frame(), quoted = FALSE, execOnResize = FALSE, outputArgs = list())
##### Arguments
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.
execOnResize
If FALSE (the default), then when a plot is resized, Shiny will replay the plot drawing commands with replayPlot() instead of re-executing expr. This can result in faster plot redrawing, but there may be rare cases where it is undesirable. If you encounter problems when resizing a plot, you can have Shiny re-execute the code on resize by setting this to TRUE.
outputArgs
A list of arguments to be passed through to the implicit call to plotOutput when renderPlot is used in an interactive R Markdown document.
##### Details

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

##### Interactive plots

With ggplot2 graphics, the code in renderPlot should return a ggplot object; if instead the code prints the ggplot2 object with something like print(p), then the coordinates for interactive graphics will not be properly scaled to the data space. See plotOutput for more information about interactive plots.

For the corresponding client-side output function, and example usage, see plotOutput. For more details on how the plots are generated, and how to control the output, see plotPNG.
