Problem Building Rstanarm in Shiny

Am not sure this is the right place to post this, please redirect me if so. It’s probably more of a Shiny thing than an rstanarm thing but wanted to double check.

App runs locally (Windows 10) but will no longer build on Shiny. Error message says the problem is building rstanarm. Am running R version 4.0.5, RStudio 1.4.1106, Rstan 2.21.2, Rcpp 1.0.6, RcppEigen 0.3.3.9.1.

Thanks much in advance.

PS I tried repeating this using the default Shiny app template in RStudio for Windows and got the same error. All I did was add library(rstanarm) at the top of the app template as follows.

library(shiny)
library(rstanarm) # I added this as test

Define UI for application that draws a histogram

ui ← fluidPage(

# Application title
titlePanel("Old Faithful Geyser Data"),

# Sidebar with a slider input for number of bins 
sidebarLayout(
    sidebarPanel(
        sliderInput("bins",
                    "Number of bins:",
                    min = 1,
                    max = 50,
                    value = 30)
    ),

    # Show a plot of the generated distribution
    mainPanel(
       plotOutput("distPlot")
    )
)

)

Define server logic required to draw a histogram

server ← function(input, output) {

output$distPlot <- renderPlot({
    # generate bins based on input$bins from ui.R
    x    <- faithful[, 2]
    bins <- seq(min(x), max(x), length.out = input$bins + 1)

    # draw the histogram with the specified number of bins
    hist(x, breaks = bins, col = 'darkgray', border = 'white')
})

}

Run the application

shinyApp(ui = ui, server = server)

Hi,
sorry for not getting to you earlier. I think this would be some sort of issue with configuration of the server (which appears to be running some kind of Linux) than with your workstation.

For debugging we would need to know a bit more about the server and get the full log - what you’ve sent is just last few lines, but usually in such cases there is much more output (I don’t know enough about shiny to help you get the full log). If the log is long, you can save it in a .txt file and attach to your post.

Tagging @rok_cesnovar who might have seen such an issue before.
