Hi Steven,

thanks a lot for your help. Below are my comments.

Cheers,

Hi Marius,

What I have found is that RSwitch does not work if you only have one instance of R.app in
your Applications folder.  RSwitch does not modify R.app in the Applications folder, so after
you switched back to R-2.13.? with RSwitch, the R-2.13 startup is interacting with the
R-2.14 R.app in some fashion that Simon Urbanek might be able to explain but which I
have not yet worked out.

When I needed both R-2.12.2 and R-2.13.1, I made a folder
called "temp" in Applications, then copied the R.app from R-GUI-5732-2.12-leopard_Leopard64.dmg
to Applications/temp and renamed it R-2.12.2_64bit.app, then moved that to the
Applications folder.  Next I copied the R.app from R-GUI-5885-2.13-leopard-Leopard64.dmg
to Applications/temp, renamed it to R-2.13.1_64bit.app, then moved it to the Applications
folder.  Now after I use RSwitch, if I run the appropriate R-<version>.app the Mac R GUI
initialization and startup works.  See e.g.

http://www.mail-archive.com/r-sig-mac at r-project.org/msg00559.html

R-GUI-5732-2.12-leopard_Leopard64.dmg and the like available from
http://r.research.att.com/

Your R.app in the Applications directory is the one from the last R you installed,
which appears to be the current development version.  So rename R.app to
something such as R-2.14.0_devel_64bit.app.

(1) I renamed it to R_2.14_devel_32bit since R.app is the one for 32bit; the R64.app I renamed to
R_2.14_devel_64bit. Afterwards, I only had R_2.14_devel_32bit.app and R_2.14_devel_64bit.app in the
Applications folder.
(2) I then reinstalled R 2.13 (from CRAN) and executed "sudo pkgutil --forget org.r-
project.R.Leopard.fw.pkg"
(3) Then, I got another R.app and R64bit.app in the Applications folder (of course)
(4) I renamed them as R_2.13_32bit and R_2.13_64bit, respectively; so I had four R*.apps in the
Applications folder
(5) Then I started Rswitch. It said: 2.13.1 for version 2.13 and <incomplete installation> for 2.14.
Nevertheless, I chose 2.14 and started R_2.14_devel_64bit.app. It crashed on startup.
(6) I then realized that this pkgutil command only works for *earlier* versions than the one installed
(7) So I then installed R 2.14 again (and also again using the pkgutil command)
(8) If I now start RSwitch, I get: 2.13.1 for version 2.13 and 2.14.0 for version 2.14; looks good,
right?

Okay, here is what I figured out:
- (8) tells me that both versions are correctly installed.
- If I start one of the versions with its corresponding *.app and RSwitch is set to this version, then
this version starts fine
- However, if I start one of the version (with its *.app) with the other version being set in RSwitch,
then I get this messy segfault output

So, it seems crucial to use the correct version on startup. It would be nice if RSwitch could select
this.

Cheers & many thanks again.

Marius

Then reinstall R-2.13.1 or use the strategy
I outlined above, and get the R-2.13.1 R.app renamed to R-2.13.1_64bit.app

Then after you use RSwitch, run the appropriate R-<version>.app

Dear expeRts,

I would like to run R 2.13 and R 2.14 on a MacBook Pro (2.53 GHz Intel Core 2 Duo, 4 GB 1067 MHz

DDR3) with Mac OS X 10.6.8. I installed Rswitch to switch between the two versions. On installing the
second version (2.14), I executed

sudo pkgutil --forget org.r-project.R.Leopard.fw.pkg
in the Terminal as suggested on the installation process. Then I finished the installation. 2.14

runs great (64-bit), but when I switch to R 2.13 and start R, I get the output below.

What did I do wrong?

Note: I previously had only R 2.14 running. Then I installed R 2.13 (because some things are not

available for 2.14). On the installation I missed the fact that R 2.14 is not available anymore [I
missed the note on using pkgutil...], so I only had R 2.13 (also running fine). After that I
downloaded R 2.14 and executed the pkgutil command during the installation process. I'm not sure if
this matters (I guess not, since that's probably the more typical way [first having 2.13 installed and
then 2.14 :-)]).

Cheers,

Marius
