And what holds you from doing the steps you described?
Create a plain text file with functions (myfunctions.R, as you want), define
its location (myproject/rfunctions/ ) and save it there.
early in every R script or project using those functions.
Another variant - you can save the functions with save() in
If you will use save(<...>, ascii=TRUE) this file will not be binary, but it
still will have an internal R format, and you won't be able to edit it.
You can add calls to source() or attach in the .Rprofile file in your local
directory or in Rprofile.site for system wide use, and your functions will
appear in R's worspace automatically. Consult with ?Startup for more
