[R] Follow-up: RStudio: Place for Storing Options (as plain text)

[G.Maubach at weinwolf.de]

Hi All,

I got a late reply from RStudio Support concerning the question where 
RStudio store options and configurations:

-- cut --

The post RStudio Config Files has a new comment. 
. . .
Unfortunately, it's unlikely that we'll be able to provide a programmatic 
R interface in the near future -- the way we lay out and store RStudio's 
client state does not make it as amenable to public consumption as we 
might hope.
That said, you can generally copy everything within that folder to a new 
machine (at the same relative path from the user home directory), and 
expect preferences to be respected + restored as you might expect.
. . .
--cut --

The result of the discussion is:

We can copy the complete RStudio directory for storing options and 
configurations under

%localappdata%\RStudio-Desktop or 
C:\Users\<username>\AppData\Local\RStudio-Desktop

and copy it completely to a new installation of RStudio.

A programmatic approach to edit RStudio options and configurations is not 
possible due to design decisions.

The purpose of the initial question was to find a way to save RStudio 
options and configurations, e g. on git/github or similar. This is 
possible by initialising the above given directory with git or similar.

An open question is what happens if a new RStudio release makes changes to 
the options and configurations. If the stored directory can be completely 
used would need additional clearification, i.e. for each new version.

Kind regards

Georg

Thanks a lot, Jeff!

And for the archives:  On reasonable OS's,  the hidden
directory/folder containing all the info is
                                  ~/.rstudio-desktop/
and if "things are broken" the recommendation is to rename that
   mv ~/.rstudio-desktop  ~/backup-rstudio-desktop
and (zip and) send along with your e-mail to the experts for diagnosis.
