RShiny:如何将滑块居中

我是RShiny的新手,我正在尝试复制此模板:https://shiny.rstudio.com/gallery/retirement-simulation.html 我确实有此模板的代码,但这是一个学习练习。

这是我到目前为止所拥有的:

ui <- fluidPage(

  # Title goes here...
  titlePanel("Retirement: simulating wealth with random returns,inflation and withdrawals"),p("Description here..."),hr(),# Sidebar layout...
  sidebarLayout(
    # Sidebar panel...
    sidebarPanel(
      # Input: Slider for the number of observations to generate ----
      sliderInput("n","Param 1",value = 500,min = 1,max = 1000),sliderInput("n","Param 2","Param 3","Param 4",max = 1000)
    ),# Main panel...
    mainPanel(
      # Outputs of any plots...
      tabsetPanel(type = "tabs",tabPanel("Plot",plotOutput("plot"))
      )
    )
  )
)

看起来不错,但我需要像上面的模板一样将滑块居中。非常感谢朝着正确方向的指针!

谢谢

您可以结合使用wellPanel,fluidRow和column。

第一个fluidRow是将2个WellPanel并排保持50%的比例。在每个wellPanel中,我们使用fluidRows定义一行,然后使用宽度为6的2列定义2个宽度为50%的列。

ui <- navbarPage("Test",tabPanel("Data",fluidRow(column(
                6,wellPanel(
                  fluidRow(column(
                    6,sliderInput("input1","input1",100,5)
                  ),column(
                    6,sliderInput("input2","input2",5)
                  )),fluidRow(column(
                    6,"input3",sliderInput("input3","input4","input5","input6",5)
                  ))
                )
              ))))

最终输出如下所示

使用margin: auto CSS规则:

div(style = "margin: auto; width: 80%",# this number can be any percentage you need
    sliderInput(
                ...
                width = "100%" # this number has to be "100%",nothing less
               )
   )
