在Shiny中刪除/隱藏sliderInput的次要刻度

[英]Removing/hiding minor ticks of a sliderInput in Shiny

我希望從sliderInput()刪除/隱藏次要刻度(不是主刻度sliderInput() 例如,在Shiny app - Old Faithful Geyser Data的默認示例中,有一個sliderInput()可以為直方圖選擇多個bin。 箱數總是整數。 因此,最好在sliderInput()隱藏/刪除次要刻度,並僅顯示bin編號的主要刻度。

Shiny app的默認示例:

library(shiny)

# Define UI for application that draws a histogram
ui <- fluidPage(

   # Application title
   titlePanel("Old Faithful Geyser Data"),

   # Sidebar with a slider input for number of bins 
   sidebarLayout(
      sidebarPanel(
         sliderInput("bins",
                 "Number of bins:",
                 min = 1,
                 max = 10,
                 value = 1)
      ),

     # Show a plot of the generated distribution
     mainPanel(
        plotOutput("distPlot")
     )
  )
)

# Define server logic required to draw a histogram
server <- function(input, output) {

   output$distPlot <- renderPlot({
   # generate bins based on input$bins from ui.R
   x    <- faithful[, 2] 
   bins <- seq(min(x), max(x), length.out = input$bins + 1)

   # draw the histogram with the specified number of bins
   hist(x, breaks = bins, col = 'darkgray', border = 'white')
   })
}

# Run the application 
shinyApp(ui = ui, server = server)

我在sliderInput()嘗試了tick = FALSE ,如下所示:

sliderInput("bins", 
             label = "Number of bins:", 
             min = 1,
             max = 10,
             value = 1,
             ticks = FALSE)

但是,這會從sliderInput()刪除所有刻度(包括主刻度sliderInput()

感謝先進的所有幫助。

您可以使用tags$style(type = "text/css", ".irs-grid-pol.small {height: 0px;}")覆蓋CSS。 CSS可以在這里找到: https//github.com/IonDen/ion.rangeSlider/issues/171

生成的sliderInput()僅顯示整數的刻度:

shinyApp(
  ui <- fluidPage(
    tags$style(type = "text/css", ".irs-grid-pol.small {height: 0px;}"),
    sliderInput("bins", "Number of bins:", 1, 10, 1)
  ),
  server <- function(input, output) {}  
)
