I have been trying to publish my shinapp and have been running into an error. Whenever I open my app using shinyapps.io it gives the error: "disconnected from the server" within 5 seconds. The app runs perfectly fine locally, however.
I checked the setting of my app on shinyapps.io and the instance size is set to large and the startup and idle timeout are both set to 60 seconds.
This is the code:
library(shiny)
library(tidyverse)
library(ggplot2)
ui <- fluidPage(
titlePanel(strong("ms_6")),
sidebarLayout(
sidebarPanel(
selectInput("countryInput", "Country",
choices = c("Choose one" = "", "Australia", "England","India", "Pakistan"))),
mainPanel(plotOutput("coolplot"))))
server <- function(input, output) {
load("./Data/data.Rdata")
output$plot <-renderPlot({
filtered <- subsetpk %>% filter(team==input$countryInput)
filtered %>% ggplot() + geom_point(aes(x = factor(year),
group = factor(bracket),
color = factor(bracket), y = prop_won),
size=2) +
labs(title = "Proportion of Matches won Sorted by Runs Scored in the \n First Five Overs", subtitle = "Sorted According to Run Bracket - Period: 2010-2017", x = "Year", y = "Proportion Won", col = "Runs Scored Bracket") + labs(caption = "Source: cricsheet.org") + theme_classic()+ theme(legend.position = "right", axis.text.x = element_text(angle = 45, hjust = 1))})
}
shinyApp(ui = ui, server = server)
These are the logs:
