图像无法以R闪亮显示 [英] Image failing to display in R shiny
问题描述
我觉得确实有一个愚蠢的错误,但是我自己解决不了,这使我发疯.简而言之,Rshiny不会显示图像.
I feel like there is really silly mistake, but I can't solve this myself and it is driving me crazy. To simply put, Rshiny is not display the image.
我将源图像放在Rscript文件所在路径的www目录中,但是出了点问题.
I put the source image in www directory in same path as the Rscript file, yet something is wrong.
我使用的代码如下:
ui <- fluidPage(
fluidRow(
titlePanel(title=div(img(height = 100,
width = 100,
src = "dummy-logo.png"), "dummy")),
sidebarLayout(...
这是我拍摄图片的途径.
This is the pathway for my image.
这是目录.
但是Rshiny找不到图像:
Yet Rshiny could not find the image:
我环顾了其他职位,但仍然不确定哪里出了问题.我敢肯定,这是一个我会感到羞耻的愚蠢错误,但是到目前为止,它使我发疯.谢谢.
I looked around other posts but I am still not sure where I went wrong. I am pretty sure this is some really dumb mistake that I will be ashamed of but as of now, it is driving me nuts. Thank you.
推荐答案
您检查了此答案吗?在闪亮的应用程序中嵌入图像
也许将titlePanel重写为:
Maybe rewrite the titlePanel to:
titlePanel(title=div(id="dummy", img(height = 100,
width = 100,
src = "dummy-logo.png"))),
然后检查图像是否真正命名为- dummy-logo.png .
And check if the image is really named - dummy-logo.png.
否则,我建议您在RStudio-> New Directory-> Shiny Web Application中创建一个新项目.将您的ui和服务器功能放在那里.创建www文件夹,将图像放在其中,它应该可以正常工作.
Otherwise i would suggest you create a New Project in RStudio -> New Directory -> Shiny Web Application. Put your ui and server functions in there. Create the www-folder, put your image in there and it should work like that.
