No no, thank you for helping To clarify, I am not out to "fix" or "change" anything, or report bugs, I just want to understand how to efficiently use R.app, my problems are
1-on my systems (one 32 and one 64), Rhistory "forgets" commands which is how this all started, and 2-I find the Startup Preferences confusing Ok, Rdata: several explained that in the workspace, a new object "x" will overwrite an old object "x" without warning, by keeping Rdata's separate one can use "x" many times for different things, I have always manually saved important Rdata's and ignored the default Rdata, but I can change, or do both now that I understand Now Directory in Preferences: I have checked Always apply and the directory is ~; the notes say dd of directory will override if not enforced; but if I dd a folder onto R, the working directory is not ~ but rather the one dd'd onto R, so does not seem "Always apply" is working Now Rhistory: again the problem is Rhistory forgets commands on my system, which is why I got into this, but then I find Rhistory(s) all over in Prefs I have checked Read on startup and the history file is ~/.Rhistory (return saves that value, thank you again, this might be in the notes) and I checked Cleanup history. It appears that if I work in some directory and then quit w save, the history is written to both ~/.Rhistory and the directory. So I had 33 .Rhistory(s) on the drive even tho I told R.app to use one. So I tried your second idea, changed the R.app history name to .xxxRhistory and voila, ".xxxRhistory" appears where R.app Preferences say and ".Rhistory" appears in the working directory, so would appear you are correct; R.app is writing out .xxxRhistory and somebody else is writing .Rhistory Now if I work in the default directory AND have R.app set to write .xxxRhistory AND quit/save, I again find in the directory both .xxxRhistory and .Rhistory, so you are again correct; R.app writes .xxxRhistory and somebody else writes .Rhistory And the .Rhistory file is written about 4 sec after the .xxxRhistory file and the .Rhistory file is 0kb So then your third idea might be correct; ie if R.app writes .Rhistory it is overwritten by the second writing of .Rhistory and if the second .Rhistory is missing commands, then it would appear that R.app is forgetting commands In sum 1-is it possible that .Rhistory from R overwrites .Rhistory from R.app and the history that R uses is incomplete so commands are "forgotten" 2-and of course what is the work around for #2 3-and lesser, what does "Always apply" do for the directory > From: Rob Goedman <robjgoed...@me.com> > Date: Tue, 05 May 2009 21:34:16 -0700 > To: Loren Engrav <eng...@u.washington.edu> > Cc: "r-sig-mac@stat.math.ethz.ch" <r-sig-mac@stat.math.ethz.ch> > Subject: Re: [R-SIG-Mac] R.app history forgets > > Loren, > > Please find my comments inserted below.
