Check your DISPLAY env var -- it defines which X11 to connect to. In your command line you have apparently set it to :0.0 while you don't have even X11 running so it will fail unless you start X11 yourself. When you request X11, Apple has some additional magic it offers to start X11 automatically - I wonder if that is broken on your system so it just hangs. That magic will show up as a path in the DISPLAY variable instead of the regular display specification. If in doubt, start X11 by hand and set DISPLAY to :0.0.
Cheers,
Simon
PS: This would be more appropriate on SIG-Mac instead...

Hello,
I have a strange problem with both R.app and RStudio.app. Since it's
a problem with both, I figure it's a problem with R or with my system,
and that your expertises may offer some leads on how I can keep
isolating the problem.
I've made it this far: when I run either capabilities() or
library(tcltk), both GUI apps hang uninformatively and have to be
force quit. On the command line (via OS X Terminal), R does fine:
"""
library(tcltk) ### shouldn't work, and doesn't, but doesn't crash/hang either
Warning message:
In fun(libname, pkgname) : couldn't connect to display ":0.0"

So far, I've tried the following solutions:
Update R
Update RStudio
Downgrade RStudio (to version 0.98.1091 from Nov 2014)
And also,
after removing all of following:
/Library/Frameworks
/Library/Frameworks/R.framework
~/Library/R
~/Applications/RStudio.app
~/Applications/R.app
~/.rstudio-desktop .rstudio-desktop.bak
~/.R
~/.Rapp.history
~/.Rhistory
~/.Rprofile
and port uninstall R
I tried installing R clean from https://cran.r-project.org/bin/macosx/
and also removing it and installing R clean from Darwin
Ports with the +tcltk variant
After all this, I'm still getting the mysterious hang in both R.app
and RStudio. I'm now out of guesses. I'm prepared to keep at it, but
at this point I don't even know where to start to continue chasing the
problem.
Thank you for your help. If this isn't the right list to reach out
to, please let me know who to ask instead.
best,
seth.
ps. This isn't a problem with sqldf, but with a more obscure package,
mwa, so the standard workaround for tcltk problems,
options(gsubfn.engine = "R"), won't do. I need to be able to run:
"""
install.packages("mwa")
library(mwa)
example(matchedwake)
"""
This code should work fine on your machines (so it isn't a problem
with the developer of mwa), but it hangs on mine at "library(mwa)"
while loading required package tcltk.
pps., specs:
