R shiny application not displaying in default window unless R Studio is restarted-CodePudding

When I go to run any R shiny application the first time it displays properly in the default R studio window. However if I go to run the code again I get a blank screen as shown below and I have to click "Open in Browser" to have it displayed properly. This happens no matter the complexity of the code even with something simple like the code below. The only way of fixing this is if I restart my R Studio entirely.

RStudio 2022.12.0 353 "Elsbeth Geranium" Release 
(7d165dcfc1b6d300eb247738db2c7076234f6ef0, 2022-12-03) for Windows

library("shiny")
ui <- fluidPage(
  checkboxGroupInput(inputId="test", label="Test", choices=1:4, inline = TRUE)
)
server <- function(input, output) {
  
}
shinyApp(ui = ui, server = server)

CodePudding user response：

You can use


shinyApp(ui = ui, server = server,options=c(launch.browser = .rs.invokeShinyPaneViewer))

to force shiny to always render in the viewer pane.
