I have a problem generating a pdf report from my app shiny which is hosted on a server. the app works fine but when I press the button to download the report, I get this error : pandoc version 1.12.3 or higher is required and was not found.

I am developing a shiny app and since I wanted to use automated testing and documentation of the function, I started to develop the interface within a package (as recommended here ). I develop this shiny app within RStudio and I have a server.R file which I can click on the Run App button within RStudio and everything works. I commit my package to a github repository and from this point I want to install it on my R shiny server using devtools and install_github function. Now I am wondering how to start my app within the server. I was naively thinking to install the package and pointing to the

I'm trying to make shiny apps available to my coworkers without them having to run or even have R installed. So I read this webpage and found this sentence: If you are familiar with web hosting or have access to an IT department, you can host your Shiny apps yourself. under the ' Share as a web page '-section. How can I do this? The problem is that my company is bound to certain restrictions regarding web hosting and security and so on, and will not (for now) pay for a shiny-server-pro. But the sentence above gives me hope to set up something ourselves to convince them. If your PC and your

How can I embed an image in a cell that is generated using the DT package so that it is displayed in an app using shiny? My example is based of this question R shiny: How do I put local images in shiny tables The example code below doesn't display the image, but rather just the url. # ui.R require(shiny) library(DT) shinyUI( DT::dataTableOutput('mytable') ) # Server.R library(shiny) library(DT) dat <- data.frame( country = c('USA', 'China'), flag = c('<img src="test.png" height="52"></img>', '<img src="http://upload.wikimedia.org/wikipedia/commons/thumb/f/fa/Flag_of_the_People%27s_Republic_of

I have a shiny app using the package shinydashboard. At first, I had all the files as 3 files - global.R, server.R, ui.R. As files got bigger and messy, I took out the codes for each menus, and placed them in a separate folder. (splitting shiny files - http://shiny.rstudio.com/articles/scoping.html ) everything works, but there's something annoying happening - it displays 'TRUE' at the bottom of the ui of the menus I split into separate folder. If everything is just in one big file, it doesn't display TRUE. anyone know why this is happening? functionally, everything is same. What's happening

In web browsers you pass parameters to a website like www.mysite.com/?parameter=1 I have a shiny app and I would like to use the parameter passed in to the site in calculations as an input. So is it possible to do something like www.mysite.com/?parameter=1 and then use input!parameter? Can you provide any sample code or links? Thank you You'd have to update the input yourself when the app initializes based on the URL. You would use the session$clientData$url_search variable to get the query parameters. Here's an example, you can easily expand this into your needs library(shiny) shinyApp( ui =

I have a shiny app that I have made that needs to get its data from another server, i.e. the other server when the shiny app is opened sends a request to the shiny app to open the app and feed it the data that it needs. To simulate this I can send the following to the R shiny app when I open the app in firefox: http://localhost:3838/benchmark-module/?transformerData=data/TransformerDataSampleForShiny.json This is a simple get request that sends the sting called : "Transformer Data" with contents "data/TransformerDataSampleForShing.json" to the shiny app. When I use the code it works fine: #
