R commander installation problem (Mac OSX Capitan)

Dear Candice,

I'm glad that you were able to get everything to work. The message offering to install additional packages on initial Rcmdr start-up is expected, as is mentioned in the R Commander installation notes.

My guess is that you didn't log out or reboot after installing XQuartz, something that the R Commander Mac installation notes tell you to do.

It's a good idea to keep the R-SIG-Mac list in the loop so that others who experience a similar problem will see the solution, so I've cc'ed the list.

Best,
 John

Hi John,

Thank you very much for your detailed explanation. I have already
checked out that webpage before posting but did not solve my problem.
Tried the tcltk check and it was not working. So I rebooted the system,
restarted R, tried to run Rcmdr and it now tells me to install some
missing softwares. Now, Rcmdr is finally working and thank you very
much!

Dear Candice,

Your message is a bit hard to read -- R-SIG-Mac list doesn't accept

HTML email and reformatted the message. Also, although you don't say so,
I assume that you're using the current versions of R and the Rcmdr
package. If you haven't already done so, please read the R Commander
installation notes at
<http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-
notes.html>.

I don't know the source of your problem but it may help to try to

isolate it. First, see whether the tcltk package -- a standard part of R
-- is working. In a fresh session, type the command library(tcltk) at
the > R command prompt and then the command
tk_messageBox(message="test") . If that doesn't work, as is likely,
you'll know that the problem isn't peculiar to the Rcmdr package.

Second, if you haven't already done so, log out of your account and

then back in -- or just reboot your Mac -- and try again. You have to
log out after installing XQuartz.

Next, try running R in a Mac terminal window (just type R at the

terminal command prompt) rather than using R.app. See whether the tcltk
and Rcmdr packages work when you bypass R.app.

Finally, try reinstalling everything -- R, the Rcmdr package, and

XQuartz. Reboot and try again.

Let us know what happens.

I hope this helps,
John

Hello, I am completely new to using R and I'm trying to install it
onto my laptop (Mac Capitan 10.11.5). I have downloaded R commander,
and also ensured I installed the latest X Quartz. I then run
"library(Rcmdr)", but received the following message: Loading
required package: splinesLoading required
package: RcmdrMiscLoading required package: carLoading required

package:

sandwichError : .onLoad failed in loadNamespace() for 'Rcmdr',

details: call:

structure(.External(.C_dotTclObjv, objv), class = "tclObj") error:
[tcl] invalid command name "tk_messageBox".Error: package or
namespace load failed for  Rcmdr I searched for help and some
previous posts suggested running X quartz in the background and
restarting R, and try again. However that failed to solve the

problem. I would really appreciate your help and advice on this.

Thank you very much Candice NUS Student
