Finding if my function inside an rscript file is been called by either an rmarkdown or an rscript

I have a function in an Rscript (this is inside an r-package of my own) that is been called either by an .R(Rscript) file or an .Rmd(rmarkdown). I need to create an if statement inside this function to do things depending if the function is called by either the Rscript or the Rmarkdown.

In my case the following solves the issue

Getting the file path that also includes filename and extension:

file_type <- try(rstudioapi::getSourceEditorContext()$path, silent = T)

Getting the file extension.

file_type <- tools::file_ext(file_type)

Then iff file_type = 'R' the functionalities are turned on and for any other cases they are off.

if(file_type == 'R'){
    ...
  }

In this specific case I only care that the extension is a '.R' and don't want to risk using the functionalities with anything else. For example if you are running the function in the console then file_type = '' and the functionalities will be off.
