shiny-server

I have developed some shiny apps which I want to make available to a few selected internal users for testing purposes and continued development. Deploying the apps on the cloud or on shinyapps.io is not an option, as the apps are handling sensitive internal data. Using ShinyServer is unfortunately also not an option, as we have a strict Microsoft only IT architecture and I thus have available only a virtual machine with Windows Server 2012 R2 on it. I have been doing some web search and have found out the following: i.) I could host my apps on the Windows machine as explained here: https:/

I have installed shiny and shiny-server on an ubuntu server. I did a similar install on a dev server which is working. R sessions when they open up load some packages. The app runs fine locally but I'm getting messages that it can't find the packages when running on shiny-server.

I have a shiny app that takes an input file in Json Runs it through a classifier and returns a classified Json object. I want the app to be able to communicate with an API. I want the API to post a file to the Shiny App which will do its work and return a classified object.

I can put this in the shiny.server file which is fine if I know the file name for the get command However the filenames coming from the API will be

I am building a series of interactive shiny web apps for a project that I am considering turning into a Company. My background is in data science and I don't have a lot of experience on the web app / server side of things, but these are important aspects for me to consider with my project. I currently have an Amazon Linux AMI EC2 instance with ShinyServer (free, open-source) installed, and I am currently hosting early versions of my web apps there. So far everything works fine, but I haven't made the links public yet. My first question is whether anyone knows if there are certain limitations

I am trying to build a Rstudio/Shiny App and post it in our intranet so that everyone else in our office could see it. I am a windows guy, and the instructions online about how to setup a shiny server within Linux environment is a bit difficult for me. Is there an easy way that I can could accomplish this goal without messing up with Linux. Even if I have to do so, is there an easy way to just have my webpage available to people within our company, not everyone on the internet. Thanks! you don't need shiny server for this, you just need to run an R instance with shiny http://rstudio.github.io
