我正在尝试将图像加载到我的shinydashboard中,当图像呈现时,我在图像的中心会出现一个蓝色问号。我在工作目录中创建了一个www文件夹,并将png放在该文件夹中。
到目前为止,此标签的布局只是:
<div class="header">
<p class="description">Description</p>
<h3 class="main title">Category</h3>
</div>
选项卡名称显示在我的shinydashboard中,它会尝试加载图像,如果我更改它会调整它的大小,但它不会加载任何内容。
有关这个原因的建议吗?

您需要将图片放在服务器端进行渲染。
试试这个:
library (shiny)
library (shinydashboard)
library (png)
###/UI SIDE/###
header <- dashboardHeader()
sidebar <- dashboardSidebar(
sidebarMenu(id = "test",
menuItem("Alignment", tabname = "AlignmentTab")
)
)
body <- dashboardBody(
tabItem(tabName = "AlignmentTab",
fluidRow(
box(
title = "Alignment", status = "primary", solidHeader = TRUE, width = 12,
imageOutput("Alignment", height = "auto")
)
)
)
)
ui <- dashboardPage(header, sidebar, body)
###/SERVER SIDE/###
server <- function(input, output, session) {
output$picture <- renderImage({
return(list(src = "/srv/samba/share/site layouts//Alignment.PNG",contentType = "image/png",alt = "Alignment"))
}, deleteFile = FALSE) #where the src is wherever you have the picture
}
#Combines Dasboard and Data together----
shinyApp(ui, server)

我尝试了以上答案。有效。我只需要稍作调整,因为我相信在imageOutput()
命令中,参数应为imageOutput("picture", height = "auto")
而不是imageOutput("Alignment", height = "auto")
。
