shiny-server

问题 Let me know if there is a way to deploy shiny dashboards as a webpage using windows server. I know it is possible using Linux but it need it for windows. 回答1: If you put below code as last lines: app <- shinyApp(ui,server) runApp(app,host="0.0.0.0",port=5050) Then to run you Shiny App in any other machine just give the IP of the machine where the code is deployed and the port number which is 5050 in this case. So, for example if you code is deployed on a machine with IP: 123.12.123.12 then

问题 I am using the renderTable function from the R Shiny package and it is returning a table with row names. Ideally I want a table to be displayed with only two columns, one for 'Month' and one for 'Value'. The output I currently get includes the row names. I have tried a few things to exclude row names but was unsuccessful. Any thoughts? output$valueTable <- renderTable({ if(input$table_view == TRUE){ data.frame(Month = Month(), Value = valueData()[,"Value"]) } }) 回答1: this instruction is

问题 I have 2 inputs, say A and B. I would like the "value" field of B to depend on the value inputted by the user for A. I.e., my suggestion for B depends on what I learnt in A. The following code does not work. How should I fix it please? shinyApp( ui = fluidPage( textInput("A", "Enter a string"), textInput("B", "Enter another string", value = "Second"), textOutput("curval") ), server = function(input, output) { if (input$A == "foo"){input$B$value <- "bar"} } ) This issue is also raised here.

问题 I know how to deploy a shiny app using http://www.shinyproxy.io/. Basically I just need server.R and ui.R. Then using docker it's a pretty easy job. However, when using flexdashboard, I only have the .rmd file. How can I implement this deploy now? 回答1: This is actually supported out of the box by ShinyProxy. You just need to add yourfile.Rmd file in the docker image (i.e. add the relevant commands in your Dockerfile), and then use the docker-cmd: ["R", "-e rmarkdown::run('/path/to/yourFile

问题 Multiple users will update a data.frame using multiple inputs in a shiny app. I'd like to be able to save every new submission (or delete actions) in the www directory of my shiny app so that the data.frame is always updated every time a user starts a new session. What would be the best way to do this? App code provided below library(shiny) library(tidyverse) library(shinyWidgets) # Define the fields we want to save from the form fields <- c("q1", "q2", "q3", "q4", "q5", "q6") # Save a

问题 I have shiny app, which works perfectly fine on my local machine. I deployed the app on shiny-server running on centos-release-6-9.el6.12.3.x86_64 .

问题 I know there are a few questions asked about this here is SO. But I couldn't figure out the solution to my problem from them. I want to Upload a file into R through shiny and assign it to an object say the object name "Object_name". I used fileInput in ui.R and did this fileInput('file1', h4('Choose Your Data File'), accept=c('text/csv', 'text/comma-separated-values,text/plain', '.OUT')) Now I accesses the "file1" and tried to recover my uploaded file through file1$datapath. I couldn't

问题 I want to create a large table to create some tables after that table in a Shiny app. This is a part of my server.R : function(input, output) { output$year <- renderText(input$year) ################################ # CONFLICTING PART OF THE CODE year <- reactive({ as.character(input$year) }) matrix = tbl_df(dbReadTable(rca_matrices_db, reactive(paste0("table_",year)))) ################################ my_table = matrix %>% ... BLA BLA BLA output$more_than_10 <- DT::renderDataTable(DT:

问题 I created an AWS instance with this R Studio AMI. The instructions point that to make the Shiny App available to public you should put it in a ShinyApps folder (public dir). The issue I'm having though, is that my apps are accesable only through that particular directory, but I can't access them through subdirectories. For instance: http://<instance IP address>/shiny/username - works http://<instance IP address>/shiny/**subdirectory**/username - doesnt work So I can't really show more than
