Is there any way that i can use button click event via shiny GUI to call a R Script? -


i trying develop gui in shiny. have made r scripts. want call r script via button click event (run r script when click on button)

i'm guessing interested in developing set of global objects. in shiny's terminology:

objects defined in global.r similar defined in server.r outside shinyserver(), 1 important difference: visible code in ui.r. because loaded global environment of r session; r code in shiny app run in global environment or child of it.

as discussed here. further on similar lines, can source scripts shiny:

# objects in file shared across sessions source('all_sessions.r', local=true)  shinyserver(function(input, output) {   # objects in file defined in each session   source('each_session.r', local=true)    output$text <- rendertext({     # objects in file defined each time function called     source('each_call.r', local=true)      # ...   }) })

i suggest have @ linked article matter of sourcing code outside server.r , ui.r discussed in detail.
