问题 I have created an app in R shiny that is practically a dashboard for KPIs.I have written it in two files, ui.r and server.r and what I am now trying to do is to add a login page and render different dashboards for different users.For example,the manager should see one dashboard and the employees should see another one.The problem is that I do not know how to convert my solution in something that uses functions and still see the html page that I have built separately before I added the login

问题 I am trying to use plotOutput in R shiny in multiple sub-menu items. However, I believe it is not possible for plotOutput to be used at multiple places with same id.

问题 Background: In my app, I have built a pop-up modal wherein users can define variables/parameters and they're subsequently stored in a reactiveValues() once an actionButton is pressed. This appears to work fine. The problem: I have a separate actionButton which is supposed to clear/empty the reactiveValues that holds the inputs above. Unfortunately, this doesn't seem to work--that is, pressing the button doesn't do anything. Minimally-reproducible code: library(DT) # UI modules sidebarCharts <

问题 I am currently using shinydashboard but I would like to have different sidbar menues associated with content in the main body. Is this possible with shinydashboard? For example: I would like to have something like this https://gallery.shinyapps.io/CDCPlot/ See how when you click on the nav bar options the sidebar menu changes as well as the body. Is that possible in shinydashboad? I like the look and feel of shinydashboard and would rather not go back to shiny. THe underlying code is here:

问题 I took the second example from http://rstudio.github.io/shinydashboard/get_started.html and the problem is that for some types of rendering the scaling is not good. Dashboard opened: Dashboard closed: Dashboard closed and open console(this time it scales the plot as it should have done from begining) Is it possible to rerender the plot when the dashboard is closed/opened? 回答1: You can force a resize event on the window when the dashboard open/close button is clicked by using jQuery to bind a

问题 Let me know if there is a way to deploy shiny dashboards as a webpage using windows server. I know it is possible using Linux but it need it for windows. 回答1: If you put below code as last lines: app <- shinyApp(ui,server) runApp(app,host="0.0.0.0",port=5050) Then to run you Shiny App in any other machine just give the IP of the machine where the code is deployed and the port number which is 5050 in this case. So, for example if you code is deployed on a machine with IP: 123.12.123.12 then
