R.app

Loren,

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?

Currently, no. For history, yes, but not for .RData, because the  
assumption is that you want to save the workspace in the directory  
that you are in at the time (many users start R and then change the  
working directory to the project directory so this behavior is  
explicitly intended). This is also the behavior in R on the command  
line. Note that you are explicitly saving the workspace, so it's not  
as if R.app is saving things on its own randomly - you actually told  
it to do so.

We could add an option that allows you to force R.app to save the  
workspace in the same location that it was loaded from or started  
(which means that you would specify that location implicitly by the  
way you start R.app). I'm slightly hesitant to do that, because it's  
not something one is used to from R, but it could be done (but then  
the .Rhistory option is already non-standard ...).

Cheers,
Simon

Using 10.5.5 and R.app 2.8.0 and MBP and MP

All seems to work fine but I have .Rhistory and .Rdata invisible
files all
over my hard drive
Can I have one of each in a known place? Is this described  
somewhere?
Yes, you can, see notes on the preferences page.

'Always apply' will help with.RData.

For .Rhistory use e.g. the setting you're trying to get accepted  
below.

Also
In Preferences if I set R history file to ~/.Rhistory and then click
on any
checkbox the ~/ is removed.  How do I stop this? Described  
somewhere?
Did you type a return after modifying the field (before clicking on
any other
checkbox)?

Regards,
Rob
