Change the value of a slider input on the client

Change the value of a slider input on the client

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

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.

    # 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))
