readRDS doesn't work before server.R

[Thomas Chauvet]

Hello,

I try to load data before the file server.R. I use the command readRDS to read this data (file .rds). But the files are not load. I put the data into a subdirectory named data.

Here's the code of server.R (the begining) :

# server.R
library(shiny)

noms   <- readRDS("data\\noms.rds")
series <- readRDS("data\\series.rds")

source('c1_simple.R')
source('c2_simple.R')
source('c3_simple.R')
source('cusum_bn.R')
source('watkins.R')
source('fonctions_test.R')


shinyServer(function(input, output) {

  serie_selectionnee <- reactive({
    series[[input$nom.serie]]
  })

etc...

Thanks for the help !

Are you running on Windows? This format:

"data\\noms.rds"

should work on Windows, but it won't work on Mac and Linux. Try using the following if not on Windows:

"data/noms.rds"

Best,

Yes, I'm running on Windows. That's why I don't understand the problem.

I also try the function load() to load a .RData but it doesn't work...

Thanks for your help !

Thomas,

So I am assuming your are running your application locally from RStudio (no Shiny Server), right?

Can you please provide more information about your environment:

- Your Windows version

- Version of RStudio

- output of sessionInfo() command 

And if you don't mind sharing your code, we could take a look it (you can send it privately if you prefer).

Thank you for your help Fereshteh. I find a solution in adding the line load(my.RData) at the begining of the ui.R.

I think my file was pretty heavy and the ui.R use a variable of this file, so the app doesn't have enough time to load the data and display the UI maybe.

Problem solved ! Thank you !
