如何将公司徽标添加到ShinyDashboard标题(不是mainPanel或mainHeader)

Question

我试着参考下面的答案,但徽标位于主面板内但不是标题面板......任何解决方案？

• 将公司徽标添加到ShinyDashboard标题中
• 在闪亮的应用程序中嵌入图像
• 使用Rstudio和knitr为每个页面添加公司徽标[复制]

我看到随机变量的分布在主面板的标题内有一个徽标,但无法在shinyDashboard标题中工作.以下是公司徽标标题的编码:

headerPanel(
        HTML('Distributions of Random Variables v4
            <a href="http://snap.uaf.edu" target="_blank"><img align="right" alt="SNAP Logo" src="./img/SNAP_acronym_100px.png" /></a>'
        ), "Distributions of Random Variables"
    ),

下面是我添加公司徽标的编码,源代码在这里.任何的想法？

dbHeader <- dashboardHeader(title = 'Reporting Dashboard',
            dropdownMenuOutput('messageMenu'),
            dropdownMenu(type = 'notifications',
                         notificationItem(text = '5 new users today', icon('users')),
                         notificationItem(text = '12 items delivered', 
                                          icon('truck'), status = 'success'),
                         notificationItem(text = 'Server load at 86%', 
                                          icon = icon('exclamation-triangle'), 
                                          status = 'warning')),
            dropdownMenu(type = 'tasks',
                         badgeStatus = 'success',
                         taskItem(value = 90, color = 'green', 'Documentation'),
                         taskItem(value = 17, color = 'aqua', 'Project X'),
                         taskItem(value = 75, color = 'yellow', 'Server deployment'),
                         taskItem(value = 80, color = 'red', 'Overall project')))
dbHeader$children$children <- HTML("<a href='http://www.scibrokes.com' target='_blank'>
                        <img align='right' alt='Logo' src='./oda-army.jpg'/></a>")

解决方案是隐藏你的图像,这样shiny渲染它就像渲染正常的dropdownMenu项目一样.

正如您可能从控制台看到的那样,dashboardHeader抛出错误

Error in FUN(X[[i]], ...) : Expected tag to be of type li

如果您尝试插入任何自定义HTML.如果你选择一个li标签,它甚至会详细说明

Error in FUN(X[[i]], ...) : Expected tag to have class 'dropdown'

所以这是你的交易,在li课程的包装中添加你的形象dropdown,你很高兴.

示例代码:

library(shinydashboard)
library(shiny)

runApp(
  shinyApp(
    ui = shinyUI(
      dashboardPage(
          dashboardHeader(title = 'Reporting Dashboard',
            tags$li(class = "dropdown",
                    tags$a(href="http://snap.uaf.edu", target="_blank", 
                           tags$img(height = "20px", alt="SNAP Logo", src="https://www.snap.uaf.edu/sites/default/files/pictures/snap_symbol_color.png")
                    )
            ),
            dropdownMenuOutput('messageMenu'),
            dropdownMenu(type = 'notifications',
                         notificationItem(text = '5 new users today', icon('users')),
                         notificationItem(text = '12 items delivered', 
                                          icon('truck'), status = 'success'),
                         notificationItem(text = 'Server load at 86%', 
                                          icon = icon('exclamation-triangle'), 
                                          status = 'warning')),
            dropdownMenu(type = 'tasks',
                         badgeStatus = 'success',
                         taskItem(value = 90, color = 'green', 'Documentation'),
                         taskItem(value = 17, color = 'aqua', 'Project X'),
                         taskItem(value = 75, color = 'yellow', 'Server deployment'),
                         taskItem(value = 80, color = 'red', 'Overall project'))
          ),

          dashboardSidebar(),
          dashboardBody()
      )
    ), 

    server = function(input, output){}

  ), launch.browser = TRUE
)

希望这可以帮助!
