Error uploading dataset to shinyapps.io

[Bob Bradley]

Hi, 

I have developed a Shiny web app that works locally, but when I deploy it to shinyapps.io, I get the following error:  'ERROR:  object 'data' not found'

I am reading in a csv file from my current working directory, which I believe is causing the problem.  Is there a way that I can upload this csv to the shinyapps.io server?  Or is there another way?

Thanks,

Bob

Just to be clear, I am able to successfully deploy the app.  However, when I try and load it in the browser, I get the object not found error.

Hi Bob,

Yes you can, you just need to put the csv file you are loading into your application in the same directory as the ui.R and server.R files. One you have that in there, just redeploy the application and you should be good to go.

Hi Tareef,

The csv file is in the same directory as those files.  For whatever reason, it doesn't come along when I deploy the app.

[Tareef Kawaf]

Hmm... we might be out of my depth here.  Are you sure that you are in that directory when you deploy the application?  Could you send us the output of the getwd() and the output of the deployApp() call?

Here's the output:

However, when I visit the website, I either get an object 'data' not found error or that it cannot establish the connection.

Bob,

Do you mind sharing your code? You can send it privately if you prefer.

It's been solved.  The error was due to a case sensitivity issue, as I was listing the file as lowercase in R, but the file was actually in uppercase.  Thanks to Tareef and Fereshteh for their help!

I have the same issue which still not resolved. Please help me overcome this issue.

I have the folder structure as 

> getwd()

"C:/Yashwanth/Retailer/5. Shiny/Apps"

Inside "Apps" directory, I have ui.R, server.R and "file.csv". I have given "data <- read.csv("file.csv")" within the "server.R".

But post deployment, it gives same error as "Error: object "data" not found".

Have you checked the output of showLogs()?

Also what is the URL for your application?

Yes I have checked & it says "Error in lapply(obj, function(val) { : object 'SA_Input' not found".

URL : https://yashwanthgowda-7488.shinyapps.io/Apps

 Note: When I use "runApp( )", it works fine but "deployApp( )" doesn't work followed to above error.

[Andy Kipp]

Sounds like you might be missing a library() call in your code. What package is SA_Input part of?

Hi  Andy !! Hope you doing well.

I have one more issue in making multiple "dataTables".

For instance I have following UI & Server,

UI.R

shinyUI(fluidPage(

  theme = shinytheme("united"),

  titlePanel("Title"),

  

  sidebarPanel(

    selectInput('level',"Select the data :",choices = c("Daily","Monthly"))

  ),

  

  mainPanel(

    tabsetPanel(

      tabPanel('Data View',column(12,offset = 1,h2('Data Input'),tableOutput('table')))

    ))

))

Server.R

shinyServer(function(input, output) {

  

  Daily <- read.csv("data/Daily.csv",header = TRUE, sep = ",", quote = "\"", dec = "." ,fill=TRUE)

  Monthly <- read.csv("data/Monthly.csv",header = TRUE, sep = ",", quote = "\"", dec = "." ,fill=TRUE)

  

  output$table <- renderTable({

                      if(input$level=='Monthly'){Monthly}

                else{

                      Daily

                      }

  })  

})

   

Note : 1. Ideally I want to select data using dropdown(selectInput) & mainPanel should display either Daily or Monthly data reactively.

          2. I tried the above method which is not working.
