Yes sorry I should have said getting the pop-up to disappear only when OK clicked isn't the problem but having the pop-up appear when the app is loaded and without a button is where I am struggling.
Here is a simple example. I created an application using File -> New -> Shiny Web App in RStudio and added the modalDialog in lines 21-26. The modal appears as soon as the app is loaded.
library(shiny)
# 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(
modalDialog(
h3("Terms of Service"),
title = "Terms of Service",
size = "l",
easyClose = FALSE
),
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)
