R help - Oct 2005 - Setting working directory interactively within a function

Is there anyway to have a function prompt the user for a working 
directory, equivalent to file.choose()?

--Paul

?setwd
e.g. setwd(file.choose())

BTW, you could have found this on your own via help.search('working
directory') . Base R has quite good docs -- you should try them first.

It's relatively easy to get a text prompt, but I don't think we've
got a
function that's equivalent to the Windows menu item "File|Change 
dir...".  We probably should.

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.
