Create an object representing brushing options
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)
||Input value name. For example, if the value is
then the coordinates will be available as
plotOutput calls may share the same
value; brushing one image or plot will cause any other brushes with the
id to disappear.
||Fill color of the brush.
||Outline color of the brush.
||Opacity of the brush
||How long to delay (in milliseconds) when debouncing or
throttling, before sending the brush data to the server.
||The type of algorithm for limiting the number of brush
"throttle" to limit the number of brush events to one
delay milliseconds. Use
"debounce" to suspend events
while the cursor is moving, and wait until the cursor has been at rest for
delay milliseconds before sending an event.
||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.
||The direction for brushing. If
"xy", the brush can be
drawn and moved in both x and y directions. If
the brush wil work horizontally or vertically.
||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
TRUE is useful if you want to clear the brush whenever
the plot is updated.
This generates an object representing brushing options, to be passed as the
brush argument of
