Sorry, but the freezing of the R-gui still persists:
Previously I had downloaded the latest version of R from the CRAN directory for
my Os X MacBook Pro (Retina, 15-inch, Early 2013). The R-gui check on R
upgrades suggested my R was up-to-date with no upgrades available.
In that situation I experienced the R-gui freeze-up that I and others have
alluded to before.
You mention way down below that this only happens in very long running
scripts using rgl and lots of memory. I don't think that's typical of
others with similar complaints. I'd guess something in the mix isn't
responding well to a memory allocation failure, but I really have no
idea what it would be.
I'd suggest running the whole thing in a debugger, and once the apparent
lockup occurs, interrupt the process and see if you can figure out what
is happening. But it isn't going to be easy.
The other suggestion would be to simplify things until you have less
moving parts involved. Does it need rgl? Does it need the R.app GUI?
Does it need whatever software you are using to produce movies? Cut it
down to a minimal reproducible example, and post that here.

On Duncans advice (Feb 11, 2 days ago) I tried the suggested nightly build and
then ran one of my R scripts from the initial directory I had set in the R-gui
preferences menu R-startup menu which was still the default det from the
previous build. R opened with the appropriately set working directory:
R version 3.2.3 (2015-12-10) -- "Wooden Christmas-Tree”
…
[R.app GUI 1.67 (7128) x86_64-apple-darwin13.4.0]
I then ran a R-script to completion. … {I read somewhere that garbage
collection is automatic and forcing it is only informational and does not
improve a situation}. Despite that I have tried garbage collection. ... And I
then tried to load another R-script into the editor from the same working
directory.
The R-gui froze with a rotating rainbow icon.
I use my Terminal window to find and kill the R-process:
Josephs-MacBook-Pro:~ josephgkunkel$ ps -x
...
6533 ?? 9:44.90 /Applications/R.app/Contents/MacOS/R
Josephs-MacBook-Pro:~ josephgkunkel$ kill 6533
I then rebooted R:
R version 3.2.3 (2015-12-10) -- "Wooden Christmas-Tree”
…
[R.app GUI 1.67 (7128) x86_64-apple-darwin13.4.0]
[Workspace restored from
/Users/josephgkunkel/Documents/Analysis/AVI_M2C_0.5/spiral/spiral1a/.RData]
[History restored from
/Users/josephgkunkel/Documents/Analysis/AVI_M2C_0.5/spiral/spiral1a/.Rapp.history]
In addition the R-script that had been loaded into the editor at the freeze was
auto-loaded.
At this point I try to load the new R-script that I had wanted to load when the
R-gui froze. ...
The R-gui freezes again (because I did not close the opened R-script and close
R and reopen it before trying to load the new R-script.
{Something is wrong with the gui at this point! Something, such as a log,
saved prior to the R-gui freezing is now directing things. Why else would a
new reboot result in a freezup with a ordinary operation. }
To run R successfully I must (1) re-kill the R process. (2) Boot the R-gui.
(3) Close any R-scripts that are brought up in the default editor. (4) Close
the R-gui using the gui red-dot icon or q(). (5) Reboot the R-gui.
When opened in this manner I can load several R-scripts into the editor but
after running any substantial R-script I should not try to load another into
the editor -or- change the working directory.
I can run another R-script.
QUESTION to Duncan: Is the above reported R version and GUI version not yet
the correct R-gui build?
One clue? After a freeze and reboot of R, the Rgui pulldown menu "File/Recent"
initially shows "Clear Menu” rather than a list. Retry still gives "Clear Menu”.
After looking there repeatedly and getting "Clear Menu” and one 'goes somewhere
else and does something else' and then comes back to "File/Recent”, a list of
appropriate old loads now appears ‘automagically’. Then the loading of a new R-script
works from this list ... but not via the “Open in Editor” icon.
Another clue: The R-scripts I run are often pretty heavy rgl library 3d
function plotting programs that load v. large data sets and then in some cases
create rotating movies that generate frames that are saved … the whole process
taking up to an hour+. Could this lead to 'memory leaks' that stomp on
critical log files or parameters/variables that save critical info for process
survival? Occasinally the R process complains that I need to shut down
non-essential processes that are using valuable memory.
Shorter uses of rgl do not cause gui freezes however the protocol to recover
from a gui freeze is still disconcertingly laborious.

With respect to the suggestion to 'tr(Y) recent nightly builds from
http://r.research.att.com/', it is the developer’s page and the link to the
R-gui nightly build loops back to the same page with no clear option of how to
load a new build of the R-gui.
There seems to be a hell-hole of problems with the recent updates of R. But my
ver R 3.2.3 GUI 1.66 Mavericks build (7060) query says that I am up to date
with nothing to upgrade. I would choose not to upgrade entire R if it is
having problems with its ‘nightly build’.
You really should try the nightly build. I am using R.app 7116 Mavericks build
in OS X 10.11.3 (El Capitan), and am not seeing these problems.
The latest build for your version of R is labelled
_"__R-GUI-7128-3.2-mavericks-Release.dm_g__".
<http://r.research.att.com/mavericks/R-3.2-branch/R-GUI-7128-3.2-mavericks-Release.dmg>
That links to
<http://r.research.att.com/mavericks/R-3.2-branch/R-GUI-7128-3.2-mavericks-Release.dmg>.
I don't see a loop.
??? what to do with this problem which was ignored the last time I posted it,
similar to Dr. Swan’s experience.
I don't know when you posted that message, but I'd guess you were given the
advice you quote above, and you didn't follow it.
