Hello, I would like to be able to save over a bookmark link when clicking the bookmark button from a restored session. Has anyone pulled this off?
Ideally, the process would work as follows...
- User starts brand new session
- User clicks 'Bookmark'
- 'On server' URL is generated (e.g. http://someip:port/?state_id=a1b2c3d4)
- User later accesses app with 'on-server' URL (http://someip:port/?state_id=a1b2c3d4)
- User clicks bookmark
- http://someip:port/?state_id=a1b2c3d4 is overwritten with new state

# Define UI for application that draws a histogram
ui <- function(request){fluidPage(
# Application title
titlePanel("Old Faithful Geyser Data"),
bookmarkButton(),
br(),
br(),
# 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,enableBookmarking = "server")
