promise/shiny/datatable works under Windows, not Ubuntu #28

Closed dmenne closed 6 years ago

dmenne commented 6 years ago

The app below creates datatable output on Windows, but not on Ubuntu. Both systems use the async branch of datatable.

library(shiny)
library(promises)
library(future)
library(DT)
plan(multiprocess)
set.seed(11)

ui <- fluidPage(# App title ----
                titlePanel("Async data table!"),

                sidebarLayout(# Sidebar panel for inputs ----
                              sidebarPanel(
                                sliderInput(
                                  inputId = "breaks",
                                  label = "Number of breaks:",
                                  min = 3, max = 8, value = 4
                                )
                              ),
                              mainPanel(dataTableOutput(outputId = "dt"))))

server <- function(input, output) {
  hardWork = function() {
    Sys.sleep(2)
    faithful$waiting 
  }

Retried after a system restart, and it works now on Ubuntu
