File browser in R

Question

I need to write a small R script for people who never used R before that imports a file and does some things with it. I would like to minimize user input as much as possible

Answer 1

It's worth mentioning rChoiceDialogs::rchoose.files. I'm not completely sold yet, but they advertise it as being completely cross platform and fixing the annoying problem common to choose.files and tk_choose.files of popping up behind other windows. See their vignette here.
