R 2.7 Port (gnu-r): Tk interface does not work

[mark.m.fredrickson@…]

The R 2.6.2 port worked with no special effort with the Tk interface. The 2.7 port does not work on my system.

Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to display "0.0"
Error: .onLoad failed in 'loadNamespace' for 'tcltk'

I have

tk @8.5.2 x11/tk tcl @8.5.2 lang/tcl

installed.

I have also tried the other drivers that my $ r --help lists with similar results.

On a similar note: why is --without-aqua a required option? What would it take to build a version that uses Quartz?

Thank, -Mark

It would seem this bug is documented (at least to some degree): ​http://www.nabble.com/tcltk-issue-remains-td16541839.html

I followed the solution mentioned there:

> Sys.setenv("DISPLAY"=":0")

Loading the Tcl/TK library then works. Knowing the problem was caused by an environment variable, I looked a little closer at what I had been doing before I launched R. I've been using R for less than a week and after launching X11, I think I had always loaded R using its complete path. However, by coincidence, after I upgraded I had been reading in my ~/.profile file to get my usual bash settings.

bash-3.2$ source ~/.profile
$ r

My .profile explicitly sets the DISPLAY=0.0. It seems OS X x11 needs DISPLAY=:0. Changing this in my .profile solves the problem.

So, in conclusion, this may not be a bug with the port per-se, but rather good old user error. I'll leave it to wiser heads to close the ticket or keep it open.

Cheers, -Mark

I'm afraid this one is user error. If you are using Leopard (10.5) then you are probably better off not setting DISPLAY and instead using default value. With this setup the OS will automatically start X11 if it is not running before trying to open any X11 devices.

As everything works fine now, I'm closing the ticket. If you have any problems just reopen the ticket/add a new comment.
