This might work for you:
You can make hidden files visible in the
Mac Finder by issuing the following
command in a *nix shell window:
in the Terminal type:
defaults write com.apple.finder AppleShowAllFiles TRUE
(see e.g. http://www.osxfaq.com/DailyTips/02-2005/02-01.ws)
Now in Finder, <Control>-click on a .Rdata file
and do "Open with" and navigate to R.app
You can associate .Rdata files with R.app
in the Info window which can be raised e.g.
by <Control>-clicking on .Rdata and selecting
"Get Info" on the pop-up menu.
I'm not sure this will all work, but may enable
you to figure out a Mac approach.
You might also want to query the R-SIG-Mac group
and check their archives.

Subject: [R] Mac GUI and .Renviron
The .Renviron and .First functions do not seem to work the same way on a
Mac OS 10.4 as on a Windows XP machine.
From working in Windows I am used to creating a new directory for each
data analysis project. In the new directory I place
First, an .Renviron file consisting of the following text:
Second, an .RData file containing a .First function designed for the
Then each project has, in its own directory, its own history.txt file of
practically unlimited size recording each command I type; I can open a
separate instance of R for each project by doubleclicking .RData in the
appropriate directory; and the .First function for a particular project
is run automatically each time I doubleclick .RData in the directory for
Now that I am on a Mac, the .RData file is invisible in Finder so I
can't doubleclick it. Typing
at the command line in the directory where a particular .RData resides
does not, for some reason, start up an R GUI session or any other
session. A little window opens up for an instant and goes away, and
subsequently no R job is running.
So as a workaround I type at the unix command line in the directory for
a given project
cp -p .RData temp.RData
and then in Finder I doubleclick temp.RData. Then an R GUI session opens
up. But this approach has the following limitations.
(a) .First function has not been run. I must manually type .First() at
the R prompt.
(b) The commands I type at the R prompt do not go into history.txt.
(c) A brand new .Rhistory file is created, clobbering any previously
existing .Rhistory file.
(d) The commands I type at the R prompt do not go into .Rhistory. That
is, after I quit R with the option "save workspace image", the brand new
.Rhistory file in my directory does not contain the commands I typed.
Is R supposed to act this way?
An alternate way to run R is to type "R" at the command line. This does
not open the GUI. And with this way of running R, there does not appear
to be any easy way to get interactive graphics.
Is there a more convenient or effective way to run R on a Mac?
Thanks for any suggestions.
