having troubles deploying an app locally

[ignacio martinez]

Hi,

I installed shiny server using docker and I'm having troubles deploying an app to that local server.

this is the error I get:

Error in shinyAppDir(x) : App dir must contain either app.R or server.R. Calls: runApp ... as.shiny.appobj -> as.shiny.appobj.character -> shinyAppDir Execution halted

The directory contains server.R, so I don't really understand what is wrong.

This is the ui.R

library(shiny)

shinyUI(fluidPage(

  fluidRow(

    column(4,

           

           # Copy the line below to make a slider range 

           sliderInput("slider2", label = h3("Slider Range"), min = 0, 

                       max = 100, value = c(-100, 100)),

           checkboxGroupInput("checkGroup", label = h3("Checkbox group"), 

                              choices = list("A1" = "A1", "A2" = "A2", "B2" = "B2", "B4"="B4", "C9"="C9"),

                              selected = c("A1", "A2", "B2", "B4", "C9"))

    )

  ),

  

  hr(),

  

  fluidRow(

    DT::dataTableOutput('tbl')

  )

  

))

and this is the server.R

library(shiny)

library(DT)

library(dplyr)

set.seed(422015)

DF1 <- data.frame(V1=sample(x = c("A1", "A2", "B2", "B4", "C9"), size = 100, replace = T),

                  V2=runif(n = 100,min = -100, max = 100))

DF1 %>%

  group_by(V1) %>%

  summarise(mean=mean(V2)) %>%

  datatable()

shinyServer(function(input, output) {

  observe({

    

    output$tbl = renderDataTable({

      DF1 %>%

        filter(V2>input$slider2[1], V2<input$slider2[2], 

               V1 %in% input$checkGroup) %>%

        group_by(V1) %>%

        summarise(mean=mean(V2)) %>%

        datatable(extensions = 'TableTools', 

                  rownames = FALSE, 

                  options = list(pageLength = 5, lengthMenu = c(5, 10, 15, 50, 100),

                                 dom = 'T<"clear">lfrtip',

                                 tableTools = list(sSwfPath = copySWF())

                  ))

    })

    

    

  })

})

Thanks for the help!

I'm having the same issue, and would also appreciate some suggestions. Did you find a resolution, Ignacio?

[ignacio martinez]

Are you on linux? chmod -R 777 /'directory where you have your app'
