I'd like to find an R package, or a way to develop on my own: how to overlay information on my windows machine.
For example, it'd be great if I could specify screen location, and overlay size, background color, font color, opacity, etc, such that a function call such as
overlay_that("this is what is being overlayed!", screen_position_data, display_parameters, display_time)
would make "this is what is being overlayed!" display in the specified location.
to be clear, I am not looking for a Shiny solution, nor any other sort of window pop-up (window or notification in taskbar). I want to overlay information wherever I want.
A package, or a nudge in the right direction would be appreciated!
