问题 Im making a shiny app, that will create 2 plots and one table. There are a lot of options in the select input part. Once selected it will subset the data.frame and return with another data.frame to be analised. It will plot accordingly and I want it to generate a report in pdf (or html) with the details of the input. Like "Generate Report" button and give me the plot for that specific input and with the input$company.pdf (or html) name. I have searched everywhere and I cant find out how to do

问题 I was wondering, if there is a way to start a shinyapp in RStudio in window mode with prespecified window size. I found a workaround via creating a new file with following code: {library(shiny) vwr = dialogViewer('modellvergleiche-irt-with-brms', width = 1600, height = 1200) runGadget(shinyAppDir(appDir = '../modellvergleiche-irt-with-brms'), viewer = vwr) } # Run app in presized window But I find it pritty ugly (especially the appDir = '../modellvergleiche-irt-with-brms' part). Is there a

问题 I cannot figure out the fault in my script's logic that causes Shiny process blocking despite trying to use async future + promises strategy. I have this (simplified) server script. It works in principle, but I don't experience parallelization. I simulate 2 simultaneous triggering and the second triggering event waits until the first one resolves. Can you please indicate what is wrong here? I have read several manuals, but I still find it hard to nail down the logic. Minimal Example, a one

问题 Problem When including a HTML document rendered from RMarkdown in a ShinyApp using shinydashboard, the HTML document is only rendered correctly when the setting "self_contained:" in the YAML chunk of the RMarkdown file is set to true. However, doing this causes you to be unable to select tabItems from the sidebarMenu in shinydashboard. Conversely, when the setting "self_contained:" is set to false, elements of the HTML document such as plots and a floating table of contents are missing (non

Shows a broken image with a question mark in the middle. ui <- fluidPage(img(src = 'imagefile.png', height = '100px', width = '100px')) server <- function(input, output) {} shinyApp(ui = ui, server = server) Any idea what is going on? 回答1: Put the image in a folder called www in the same directory, so you have www/imagefile.png.

问题 I am working on a shiny application and have used shinydashboard package for the UI part. I want to open the sidebar on hover instead of click on the button.
