Dear users,
I am looking for a function to choose a folder interactively, just like
file.choose() but for a folder.
"choose.dir()" does exist on Windows, so you could switch to that OS, or
write your own equivalent for MacOS.
Is this the sort of thing for which a patch to the Mac-specific code
would be welcomed/of some interest by R-Core or are their good reasons
this doesn't already exist?
Yes, it would be of interest. It would need to rely on Aqua/Quartz and
be written in Objective-C: unless something is done for the Quartz event
loop in command-line R (which is not impossible as the quartz() device
does so), it would be confined to R.app.
The main constraint is that we have very few people who know enough
about Mac GUI programming (and Objective-C) and R internals.
It was simple enough on Windows as we already had choose.files (and a
GUI for file.choose): that would also be worthwhile on a Mac. We also
has someone keen enough on Windows GUI programming (although he did not
last long).
Michael
