Create an object representing brushing options
This generates an object representing brushing options, to be passed as the
brush argument of imageOutput or
plotOutput.
Usage
brushOpts(id = NULL, fill = "#9cf", stroke = "#036", opacity = 0.25,
delay = 300, delayType = c("debounce", "throttle"), clip = TRUE,
direction = c("xy", "x", "y"), resetOnNew = FALSE)Arguments
- id
- Input value name. For example, if the value is
"plot_brush", then the coordinates will be available asinput$plot_brush. - fill
- Fill color of the brush.
- stroke
- Outline color of the brush.
- opacity
- Opacity of the brush
- delay
- How long to delay (in milliseconds) when debouncing or throttling, before sending the brush data to the server.
- delayType
- The type of algorithm for limiting the number of brush
events. Use
"throttle"to limit the number of brush events to one everydelaymilliseconds. Use"debounce"to suspend events while the cursor is moving, and wait - clip
- Should the brush area be clipped to the plotting area? If FALSE, then the user will be able to brush outside the plotting area, as long as it is still inside the image.
- direction
- The direction for brushing. If
"xy", the brush can be drawn and moved in both x and y directions. If"x", or"y", the brush wil work horizontally or vertically. - resetOnNew
- When a new image is sent to the browser (via
renderImage), should the brush be reset? The default,FALSE, is useful if you want to update the plot while keeping the brush. UsingTRUE<
