Saving a *.R file hangs R GUI under certain sequences of operations

Duncan?

I?m creating a new file. The menu item is ?New Document?.   I called it
*.R to distinguish it from ?New Rd Document?, and since when you
attempt to save it the suggested name is ?untitled.R?.

I don?t see anything in the console.  When I click an existing folder
in the dialog, there is a brief delay and then the pinwheel, then it?s
stuck.

I have found a sequence of actions that causes the R GUI on Mac to

1. Launch R GUI.
2. Open an empty *.R file via the button or menu or shortcut.

Could you clarify this:  Are you opening an existing file that is

empty, or creating a new document?  I don't see any way to specify *.R
in the former, and I don't see a problem with the latter.  A bit more
below...

3. Add something to the file.
4. Save the file via menu or shortcut (technically a Save as?).  In

the save dialog box:

  a. If you save in whatever directory is pointing to, everything

works fine.

  b. If you attempt to change the directory, for instance by

clicking on the icon for a folder w/i the current directory, one gets
the pinwheel of death and R must be forced to quit.

Can anyone else reproduce this?

R version 3.6.1 (2019-07-05)
Platform: x86_64-apple-darwin15.6.0 (64-bit)
Running under: macOS Mojave 10.14.6

I'm using the same R, but macOS High Sierra 10.13.6.

At some point in the exercise I saw this warning in the console:

objc[27995]: Class FIFinderSyncExtensionHost is implemented in both

/System/Library/PrivateFrameworks/FinderKit.framework/Versions/A/FinderKit
(0x7fffadb52cd0) and
/System/Library/PrivateFrameworks/FileProvider.framework/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/FinderSyncCollaborationFileProviderOverride
(0x112670cd8). One of the two will be used. Which one is undefined.

It might be that in the newer MacOS this is fatal.
