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
There are several Terminal incantations that will make the default for
Finder.app to display hidden files. Apparently you have your desktop
machine set to one style and the other is still in the default mode.
Here's how to change it. From a Terminal window:
defaults write com.apple.Finder AppleShowAllFiles YES
And then restart the Finder with option-click on the Funder icon and
choose relaunch. (or an alternative in the Terminal session would be
to type: killall Finder )
The reverse effect is obtained by repeating with NO instead of YES.
The "hit return" after entering the path/name might be what you are
missing
All assuming you have done nothing with .Rprofile
