Re: [R] Query concerning working directory for file.choose()
Thanks Duncan. The behaviour is tricky, and I'm still not sure I can predict
it. Indeed,
I spent about an hour fiddling with file.choose(). It allows navigation across
directories,
so is not totally without value. However, I've noticed users are very prone to
making errors
when they aren't in the "right" place, and my application is for non-technical
users. In fact,
it is a tool to help people pay bills and get documents online who are new to
computing,
or at least to online processing of payments and reports (Canada Post strike in
mind!)
and process them in a planned and orderly way so records are safely kept.
(Yes, I realize R is an odd choice, but is IS cross-platform, and the working
example uses
YAD in Linux for the dialogs.) I'll welcome discussion of this project offline.
Eventually
it should be on Github.
svDialogs seems promising, and I'm now exploring that, though I was
disappointed to find
a note (on page 17 of 19 in the pdf manual no less) that "some functions are
not working
yet in MacOS". Tests will be needed.
Cheers, John Nash

Front ends are allowed to replace the underlying function, so that may depend on which front end you are using. I'm
talking about R.app on a Mac.

Re: [R] Query concerning working directory for file.choose()
Yes, this is different in RStudio, e.g.
I had actually forgotten how brain-dead the CLI version is:
> file.choose()
Enter file name:
(Given that install.packages() fires up a Tcl/Tk chooser, users might
reasonably expect us to do something at least slightly smarter).

Re: [R] Query concerning working directory for file.choose()
I believe file.choose() remembers the last choice, and repeats that
location the next time you call it. This is true when it is called at
top level or from within a function.
The first time you call it in a session, it will default to the current
working directory, but not after that.
Front ends are allowed to replace the underlying function, so that may
depend on which front end you are using. I'm talking about R.app on a Mac.
