[R] Setting working directory interactively within a function

[Berton Gunter]

Oops. Thanks, all. Egg on my face. I forgot about that little detail (on
Windows, anyway).

However, you can still do it via dirname(file.choose()) to get the
directory, on Windows,anyway, right? If that isn't implemented on another
platform, than you could mimic the dirname() code by using gsub() to trim
off the last file part of the path to get your directory.
