[R-SIG-Mac] R.app intractable history problem

[Loren Engrav]

I also found the R.app management of .Rhistory difficult to understand
Finally gave up trying to understand and did this

In 64 bit R on Mac Pro

Checked Read history file on startup

Then entered ~/.engravRhistory in the R history file: AND HIT RETURN

(whole things fails if you do not hit return)

Checked Cleanup history entries

Now have visible file called engravRhistory.Rhistory in home folder and
history loads Ok at startup

Is not pretty but am no longer fiddling with history file and losing command
history

Then in 32 bit on MacBook Pro

Did same thing but here the file is named .engravRhistory and is invisible,
but still works

The "hit return" after entering the path/name might be what you are missing

All assuming you have done nothing with .Rprofile
