Renders a reactive plot that is suitable for assigning to an
renderPlot( expr, width = "auto", height = "auto", res = 72, ..., env = parent.frame(), quoted = FALSE, execOnResize = FALSE, outputArgs = list() )
An expression that generates a plot.
- width, height
Height and width can be specified in three ways:
"auto", the default, uses the size specified by
offsetWidth/`offsetHeight`` of the HTML element bound to this plot.)
An integer, defining the width/height in pixels.
A function that returns the width/height in pixels (or
"auto"). The function is executed in a reactive context so that you can refer to reactive values and expression to make the width/height reactive.
When rendering an inline plot, you must provide numeric values (in pixels) to both
Resolution of resulting plot, in pixels per inch. This value is passed to
grDevices::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
grDevices::png(). These can be used to set the width, height, background color, etc.
The environment in which to evaluate
expra quoted expression (with
quote())? This is useful if you want to save an expression in a variable.
FALSE(the default), then when a plot is resized, Shiny will replay the plot drawing commands with
grDevices::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

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.

expedite the rendering of identical plots.
