图片没有在Shiny app R中显示 [英] Image not showing in Shiny app R

问题描述

我有一个想要嵌入我的闪亮应用程序的图像，并且已经阅读了尽可能多的关于如何操作的内容。虽然，当我运行我的代码时，我得到的只是一个蓝色问号。

I have an image i'd like to embed into my shiny app, and have read as much as I can find on how to do it. Although, all I get is a blue question mark when I run my code.

这是我在 fluidPage中添加的代码行 ui command

This is the line of code I have added, within the fluidPage ui command

img(src="logo.png", align = "right",height='100px',width='400px')

我的图片已放置在项目目录文件夹中，并尝试在名为www的单独文件夹中（根据此处提供的建议）

My image has been placed in the project directory folder, as well as trying in a separate folder inside named www (as per suggestion given here)

编辑：以下语境中使用的代码：

Code used in the following context:

ui <- fluidPage(titlePanel("Test title"),

                img(src="logo.png", align = "right",height='100px',width='400px'),

                hr())

推荐答案

在回到这个问题之后，我发现解决方案是简单地格式化Shiny代码，命名为e R文件 app.R ，然后单击运行App ，而不是选择所有代码并在控制台中运行。

After coming back to this problem, I found that the solution is to simply format the Shiny code properly, by naming the R file app.R, and clicking Run App as opposed to selecting all of the code and running within the console.

不确定这会产生什么影响，为什么会有所不同，但是我做过的众多Shiny应用程序在执行此操作时都得到了解决。

Not sure how or why this makes a difference, but the numerous Shiny applications I have worked on since have all been resolved when doing this.
