updateSliderInput: Change the value of a slider input on the client

Description

Change the value of a slider input on the client

Usage

updateSliderInput(session, inputId, label = NULL, value = NULL)

Arguments

session

The session object passed to function given to shinyServer.

inputId

The id of the input object.

label

The label to set for the input object.

value

The value to set for the input object.

Details

The input updater functions send a message to the client, telling it to change the settings of an input object. The messages are collected and sent after all the observers (including outputs) have finished running.

The syntax of these functions is similar to the functions that created the inputs in the first place. For example, numericInput() and updateNumericInput() take a similar set of arguments.

Any arguments with NULL values will be ignored; they will not result in any changes to the input object on the client.

Examples

## Not run: 
# shinyServer(function(input, output, session) {
# 
#   observe({
#     # We'll use the input$controller variable multiple times, so save it as x
#     # for convenience.
#     x <- input$controller
# 
#     # Similar to number and text. only label and value can be set for slider
#     updateSliderInput(session, "inSlider",
#       label = paste("Slider label", x),
#       value = x)
# 
#     # For sliders that pick out a range, pass in a vector of 2 values.
#     updateSliderInput(session, "inSlider2", value = c(x-1, x+1))
# 
#     # An NA means to not change that value (the low or high one)
#     updateSliderInput(session, "inSlider3", value = c(NA, x+2))
#   })
# })
