在 R Shiny 标头中制作图像超链接

我一直在尝试将图像输出超链接到网站，但我在仔细阅读有关堆栈溢出的其他问题时遇到了麻烦

带有闪亮的可点击链接的 svg - 不可点击 https://stackoverflow.com/questions/37121767/svg-with-clickable-links-in-shiny-not-clickable

server.r

library(shiny)
library(png)


server <- shinyServer(function(input, output) { 

output$image1 <- renderImage({
  width<- "100%"
  height<- "100%"
list(src = "www/logo.png",
     contentType = "image/png",
     width = width,
     height = height,
)

}, deleteFile = FALSE)
output$text1 <- renderText({ "please help make the image hyperlinked"     })


})

ui.r

library(shiny)



ui <- shinyUI(pageWithSidebar(
 titlePanel(imageOutput("image1")),

sidebarPanel(
  helpText(   a("Click Here for the Source Code on Github!",         href="https://github.com/Bohdan-Khomtchouk/Microscope",target="_blank"))

 ),
 mainPanel(
tabsetPanel(


  tabPanel("Instructions",textOutput("text1"))
))
))

您可以将 logo.png 替换为您想要的任何内容，我认为超链接会出现在服务器的列表中。

只是包裹imageOutput with tags$a所以在用户界面中：

titlePanel(tags$a(imageOutput("image1"),href="https://www.google.com"))

如果你想从服务器端定义网页，那么你需要这样的东西：

#server
  output$example <- renderUI({
    tags$a(imageOutput("image1"),href="https://www.google.com")
  })
#UI
titlePanel(uiOutput("example"))
