I deployed a flexdashboard shiny app to shinyapps.io, which worked fine. However, I want the dashboard to automatically update when the data file on google drive updates. What are my options for setting this up? I don't want to continously manually deploy a new version to shinyapps.io.
I was looking for the same, and I found the following :
Option #1 : you can try to connect to a data base using shinyapp.io
ref: https://docs.rstudio.com/shinyapps.io/applications.html
Option #2 : you can work with RStudio Connect
After doing some research, I would go with option 2, because :
you set up an environment to publish your dashboard.
you have the right environment to maintain, control and update the data.
The following article explains the steps to set up an environment to answer the need

The following article allows you to understand the difference between shinyapp.io and RStudio connect.
Initially I pusblished my dashboard in Shinyapp.io, buying a monthly licence, but now I realized RStudio Connect was a better choice.
To understand the difference, I am posting the following comparison:

I've some shiny app and I want to execute and to make it standalone application (it will be awesome if it will open via chrome).
I can't upload the app to the Net and I want that also co-workers without R studio or R
will use this app.
because of the security company - I can't download any software except R packages.
I saw here a few solution, but all of them included any software download.
I have done some research on this issue. The commenters are basically correct: you need the R binaries in some way, either a portable R or an R server. But there are solutions that allow it to bundle those with your code and hide the details from your users.
On option is to wrap your app along with
a portable R into a container application like Electron. The electron-quick-start project tries this.
The RInno package provides functions to bundle your app and R portable into an installer app. Every user runs the installer on their system once which will install your app, the packages and the code. But in the end users may not see the difference to other apps. They get a link in the start menu and that's it. I did that successfully. But it did not work out of the box. I had to adjust the output manually in several places.
A second container solution works with docker. That is what ShinyProxy does. See also this blog.
The package shinyShortcut (I quote) "will produce an executable file that runs the shiny app directly in the user's default browser".
Important to note: I haven't tested most of them. From reviewing the solutions I often get the feeling that these solutions might make releases somewhat complicated because there are always manual steps involved.
I have built a shiny app that I have successfully deployed to shinyapps.io in the past. However, since I need better hosting resources and a custom domain, and the only shinyapps.io option allowing for the latter is out of my price range, I am trying to host the app on a digital ocean ubuntu droplet.
I have been able to set up shiny server on my droplet using this tutorial. The sample apps work just fine. However, when I try to access my own app (having uploaded it into a directory within my shiny server) I get the following error:
An error has occurred! An error has occurred. Check your logs or
contact the app author for clarification.
I've googled for a solution and have tried moving the data cleaning steps from outside the server/ui function into the functions. I have also checked that RStudio on the droplet has all the required packages installed and that seems to be the case. I have checked the logs but there is nothing about this app or the error in the shiny server log. My app works fine both on my local computer and on shinyapps.io. I'd really appreciate any pointers (and apologies if I am duplicating but I haven't found anything that seems directly applicable).
Okay - it turns out one of the packages was indeed missing. I had installed them all using my non-root user with admin privileges, and was under the impression they were available globally. One of the packages was not available to root and installing it there resolved the problem.
The shinyapp I built earlier was running fine in my old laptop. Recently I got a new laptop with Windows10. After setting up everything, I tried to run the app but it the browser opens and closes immediately with the error :
Listening on http://127.0.0.1:5004
ERROR: [on_request_read] connection reset by peer
I have also set chrome as default browser....
I deployed this app in shinyapps.io it is working fine there.
I tried few more simple apps in Rstudio but the same issue coming. Looks like the issue is more related to some setting in Windows10. Can someone help me please.
Thanks in Advance.....
Without details on the specific code, I'd share my personal experience with the same error for your reference. In my case, I used RStudio to create a shiny app that save data to a local directory on my computer, while I told R to output files to directory "response", I hadn't created such directory under the working directory so came the error. Simply creating the sub directory named "response" solve this right away. Or for moving your project files to different places in the future, you can just check whether the folder exists, if not, create one shall save you a lot of time.
I have a shiny app that works locally even as a shiny app. However when I deploy it in a Shiny Server(free) running on RedHat 5 within my organization, there are strange issues with gsub. To debug this, I would like to see the data at different instances in the shiny code. So, is there something like console.log as in javascript?
I checked the documentations like the one here http://shiny.rstudio.com/articles/debugging.html, but they talk only about a shiny app running within RStudio which is not my case.
Note:
1. The code that I want to use is not within the server function of the shiny app.
2. I cannot install new packages, because of IT restrictions
3. I don't have access to shiny server logs
Hope the question is clear.
I am working on the Shiny tutorial for RStudio. I updated my RStudio, as indicated in the tutorial. The current version I have is 0.98.945. When I run the supplied examples like runExample("01_hello"), it opens my web browser and shows all the HTML content, but does not seem to be processing the R code.
When I proceed further in the tutorial for creating my own app runApp("App-1"), I get an error message on the web page: ERROR: could not find function "fluidPage". After some sleuthing, I found a posting on another site indicating that I need to download the developer version of shiny from GitHub, found here. I ran the code snippet for that installation -- and still no luck. Any suggestions would be greatly appreciated!
After updating Rstudio to the newest version redo the install.packages("shiny") and library("shiny"). Once you do this it should eliminate the need to manually do the runApp code and a button should appear were the run button usually is that says run app. before you can click run app though you have to set your working directory to the location were you have saved your server.R and ui.R by going to session -> set working directory -> choose directory. chose the folder location then click run app.
Edit: there should be no need for you to run that code from GitHub
I had the same problem. After installing shiny, I had to restart Rstuido for the "Run App" button to appear.
I had also some wired troubles when starting using shiny. Finally I got all fixed by removing all my previous libraries and installations and re-install only the latest versions
