css - 删除shinydashboardPlus中的左侧边栏(仅保留右侧)

Question

是否可以完全删除 shinydashboardPlus 中的左侧侧边栏，但保留右侧？

我尝试省略对参数 sidebar 的调用，但此参数是必需的，因此我收到错误。我想要的是实现这一目标(没有左侧边栏，只有右侧边栏)。

示例代码

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
data(iris)

header <- dashboardHeaderPlus(
  enable_rightsidebar = TRUE,
  rightSidebarIcon = "filter"
)

sidebar <- dashboardSidebar(selectInput(inputId = "slect",
                                        label = "Selection Menu", 
                                        selected = "a",
                                        choices = LETTERS[1:3])
)

body <- dashboardBody(fluidPage(plotOutput( "scatter", 
                                  height = "700px", 
                                  width = "700px")))

rightsidebar <- rightSidebar()

ui <- dashboardPagePlus(header, 
                        sidebar, 
                        body, 
                        rightsidebar)

server <- function(input, output) {
    output$scatter <- renderPlot({
    plot(iris$Petal.Length, iris$Petal.Width, pch=21)
      cats <- levels(iris$Species)
      cols <- c("red", "blue", "yellow2")
      ind <- lapply(cats, function(z) which(iris$Species == z))
      for (i in seq(cats)) {
        points(iris$Petal.Length[ind[[i]]], iris$Petal.Width[ind[[i]]], 
               pch = 19, col = cols[i])
      }
    })
}

shinyApp(ui, server)

抱歉，现在时间有限，但请检查您的第一个问题:

library(shiny)
library(shinyjs)
library(shinydashboard)
library(shinydashboardPlus)
data(iris)

header <- dashboardHeaderPlus(
  titleWidth = "0px",
  enable_rightsidebar = TRUE,
  rightSidebarIcon = "filter"
)

sidebar <- dashboardSidebar(
  width = "0px"
)

body <- dashboardBody(
  useShinyjs(),
  fluidPage(plotOutput( "scatter",
                        height = "700px", 
                        width = "700px")))

rightsidebar <- rightSidebar()

ui <- tags$body(class="skin-blue sidebar-mini control-sidebar-open", dashboardPagePlus(header, 
                        sidebar, 
                        body, 
                        rightsidebar))

server <- function(input, output) {
  hide(selector = "body > div > header > nav > a")
  output$scatter <- renderPlot({
    plot(iris$Petal.Length, iris$Petal.Width, pch=21)
    cats <- levels(iris$Species)
    cols <- c("red", "blue", "yellow2")
    ind <- lapply(cats, function(z) which(iris$Species == z))
    for (i in seq(cats)) {
      points(iris$Petal.Length[ind[[i]]], iris$Petal.Width[ind[[i]]], 
             pch = 19, col = cols[i])
