在 Jmeter 板标题中添加徽标不适用于bs4Dash库。有什么建议吗？

# app.R ##

library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(# removed some lines
    title = div("", id = "home_logo", a(href = "#Home",

    controlbarIcon = shiny::icon("filter")
    
  ),
  dashboardSidebar(
    collapsed = TRUE

使用img-标签如何：

title = tags$img(src = 'https://www.r-project.org/logo/Rlogo.png', title = "Rlogo", height = "40px")

完整示例，包括链接：

library(shiny)
library(bs4Dash)

ui <- dashboardPage(
  dashboardHeader(title = a(target="_blank", href = 'https://www.r-project.org/',
                              img(src = 'https://www.r-project.org/logo/Rlogo.png', title = "Rlogo", height = "40px"),
                              style = "padding-top:5px; padding-bottom:5px;")),
  dashboardSidebar(),
  dashboardBody(
    # Boxes need to be put in a row (or column)
    fluidRow(
      box(plotOutput("plot1", height = 250)),
      
      box(
        title = "Controls",
        sliderInput("slider", "Number of observations:", 1, 100, 50)
      )
    )
  )
)

server <- function(input, output) {
  set.seed(122)
  histdata <- rnorm(500)
  
  output$plot1 <- renderPlot({
    data <- histdata[seq_len(input$slider)]
    hist(data)
  })
}
