shiny-server | Host Shiny applications over the web | Data Visualization library

Say that I have this code (which is modified from OpenStreetMaps autoplot error in RStudio Server and Shiny Server in R4.0.0):

I'm building a WebApp with a SQL DB as Backend. I'm Deploying the both parts on Azure, as Azure Webapp and SQL Server.

The SQL server is sercured with Azure AD (AAD). So only Users in a Group can access the DB.

So I'm trying to setup a workflow where the Webapp login the user and collect his Access token. And then uses the token to Query the SQL server.

I've registreted the App in AAD, where it is authorized to read the user ID and impersonate as the user.

I've the following code which is working local. But I can't get it to work deployed locally in a Docker Image.

Trying to have a pie (or preferably, donut) chart that displays totals per category and that allows a drilldown to display specifics per category when clicked. Make sense?

I think I might not have every system setting correct, since also copy/paste standard examples render an empty page. Unless that's somehow outdated or something. My system: Ubuntu 20.04, R 4.0.5, packageVersion("shiny") 1.6.0, shiny-server --version 1.5.16.958 Blank examples: https://plotly-r.com/linking-views-with-shiny.html#drill-down and Creating drill down report in R Shiny (amongst others)

My current attempt (not reactive yet because I can't for the life of me figure it out):

I am deploying Shiny-server in container. By default Shiny-server listens on port 3838, here is piece from shiny-server.conf

I am building app where a user can make edits to a datatable and the hit a button to reflect the changes in a non-editable copy of this datatable (in the final project, I will need to have two datasets that need to be matched manually), but for now this small MWE shows the problem I have with making a copy of the reactive table in which changes can be made, without changing the data of the original reactive table. I would like to make this app work, where you click edit a cell in the table dat_joined$data/output$mytable and that those changes do reflect in a new table mydf$data/output$table2. To do mydf$data initially (before any changes are made) needs to be a copy of dat_joined$data This is a follow up on this question and answer: how to make a copy of a reactive value in shiny server function

I am trying to develop a shiny app to predict the price of diamonds based on carats using the "diamonds" data on R. Everything works except the plot section which returns an error: object "carat" not found. the code seems to work outside of shiny so I am guessing the problem is with reading in the dataset into the shiny-server. I am a novice with regards to shiny and I have explored similar problems on here and came up short, I would like to know what I'm doing wrong. I tried to attach the images of the error and the expected output in this query. Thank you!

I have a shiny application that uses a csv file to generate different figures. I upload my application in my personal linux server using shiny-server. I use this structure for my application

• global.R
• ui.R
• server.R

Inside my global.R file I have this line, which help me to load and read my csv file

I am trying to run a ShinyApp via R studio. The R Studio is on my work computer and I am accessing it from my home computer via remote access.

I tried changing the host argument in runApp to "0.0.0.0" (as suggested:here ) and even then all i get is a dark blank screen.

Any help, appreciated.

When I use the plotly library in a shiny-server I have the following issue:

The app will work correctly using "Run App" command in RStudio Server, but when deployed on the shiny-server:3838 it gives the following error Error in library(plotly) : there is no package called ‘plotly’ Calls: runApp ... sourceUTF8 -> eval -> eval -> ..stacktraceon.. -> library Execution halted

It seems that plotly library for some reason is not installed in shiny-server although it is installed and working for RStudio Server. Does anyone know how to fix it.

I initially thought it could be an issue with my code, but I can actually replicate the exact same issue if I use a code sample provided by plotly-r website here

The code to replicate is below:
