shiny-server

问题 Note : I have read almost all the discussions on this object in shiny googlegroups and here in SO. I need an indicator that shows the shiny server is busy. I have tried shiny incubator, however, the problem is that I can't set a max for progress bar. I don't want something like this : http://shiny.rstudio.com/gallery/progress-example.html What I need is something that: 1- shows a busy indicator message and bar (i.e just a simple animated bar, do not need to show a filling bar) as long as the

问题 This is not yet a practical question but rather a theoretical one. I was thinking of using Shiny to display some raw data in an interactive way. This is fine. However - is it possible to have users change the data that is displayed? Say, if I have a bunch of sliders for users to restrict the underlying data to satisfy certain conditions and have these observations displayed - is it possible to allow the users to make modifications to that data and have these modifications sent back to the

问题 I have a sql query below that works just fine. Select * from dbo.Employee where StartDate between '08/01/2014' and '08/31/2014' order by StartDate I am modifying this query such that it takes date input from shiny UI (daterange) . sqlQuery(myconn, paste("Select * from dbo.Employee where StartTime between", "'as.character(input$daterange[1])'", "and", "'as.character(input$daterange[2])'", "order by StartTime")) I get an error [1,] "22007 241 [Microsoft][SQL Server Native Client 10.0][SQL

问题 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

问题 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>',

问题 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

问题 Maybe it is a silly question but I am really confused. We have Shiny server running on Linux system and set language = UTF-8 to ensure it shows special characters correctly (e.g. 谭盾, いきも,Acatlán de Pérez Figueroa). However, when I tried to download the data (I have a download button utilizing write.csv function), those special characters got mess up. When I specify the encoding, it works well for both Windows and Mac systems, meaning both Windows and Mac users are able to download correct

问题 I am creating a shiny app that will do the following using Spotify's API: 1) You manually type in the Artist Name 2) In the selectInput, the albums need to automatically populate for your selection. 3) After selecting the album, a table in the main panel will show the songs, artist, and album. I have this working so far but I cannot figure out how to do the 2nd part which is to automatically populate the albums once the artist is selected. I asked a previous question here: Shiny: Automatic
