Loren,
Please find my comments inserted below. Thank you for being persistent!

Ok, so Rdata goes to the directory one is working in; and so will have

As a counter example, I work on 5 or 6 different projects
simultaneously,
each in its own directory sub tree. Several of the projects need to
store the
workspace after I'm done. This is implemented as the default mechanism.
Through the .Last mechanism you can get your desired behavior. But
unfortunately, it will take some extra work to define the .Last
function.
That should take care of many .RData's.
As for Rhistory if one declines to save workspace, Rhistory is
written to
the directory specified; if one saves workspace Rhistory is written
to both
the directory specified and the workspace directory, ie to both;
this also
seems strange.
Could it be R, not R.app that creates the .Rhistory file if the
workspace is
saved????? I am not aware of this behavior (the fact that R creates a
history file when asked to save the workspace), or simply might have
missed it if it was introduced in the 4 or 5 years since I worked on the
history mechanism for R.app.
And the troubled history is attached
This seems problematic; not knowing where these files are going and
winding
up with many; and then the forgetful Rhistory as well
And indeed, in that case, if the name of the history file set in the
R.app
preferences is the same as R's default name (.Rhistory) ***and*** the
workspace is saved, the history file seems to forget recent commands
because R.app writes its history file which is subsequently overwitten
by R.
Maybe someone familiar with the R source can confirm this behavior, I
have
rarely looked at the R source, just at the R.app code.
Rob
Thank you

Loren,
Thanks for the screen shot.
A bit more experimentation and a quick look at the code refreshed my
memory.
If you exit R, .RData is always written to the directory you are in.
In your setting, on q() to quit, R.app should ask for conformation to
save the workspace.
If you don't change your directory it should create a .RData in your
home directory (that's where your R.app started).
Preferences do not provide help here, but you could create a .Last
function with a save.image() command in it to force storing
the .RData
file to a fixed directory. In that case you can opt to set the Quit
preferences to 'No' (don't ask me to store the workspace).
For history its a (tiny) bit more flexible. By selecting an absolute
path, like you have in your setting, it will always store the current
available history commands in that file (including the ones that were
read in during startup, so the new commands are at the end of the
file).
If this does not work for you, can you send me your ~/.Rhistory file
after executing a last new command in R.app, maybe something like
'testHist <- 1' and quitting R.app?
As you found in the archives, a few folks did have trouble (usually
because R.app could not write to the selected directory).
After this email it might be better to take this discussion off-line.
Regards,
Rob

Loren,
Can you send me a screen copy of the Startup preferences ( with the
cursor inside the Startup Preferences window, press Command-
Shift-4,
followed by pressing the spacebar, followed by a click of the mouse
button, this should write it to your Deskop as 'Picture 1').

Mac OS 10.5.5 and R.app 2.9.0
I start up, run a few things, and quit (w or wo save) and no
directory
changes
Then I restart and the recent commands are no longer in Rhistory
The only box I have checked in History preferences is Read on
Startup and I
have max entries set to 5000
I see queries about this before but I could find no solution
Thank you

The return before clicking anywhere else solved that problem, clever
So I trash all invisible .Rhistory and .Rdata files
Then made a new folder (called R_History_Data) and aim Preferences
at this
folder (using the return)
Then run R.app and yes, I have one .Rhistory and one .Rdata in that
folder
But then I change the working directory and do some stuff
Then quit and save working directory
And now I have two of each invisible files, one in R_History_Data
and one in
the working directory folder
So it still appears as I move from directory to directory I will
leave
invisible .Rhistory and .Rdata files all over
Is it possible to have Rhistory and Rdata always written to the
R_History_Data folder?
