Can't load X11 in R after OS X Yosemite upgrade

Running into the following error when I try to use ggplot2 and plot within the console after upgrading to Yosemite:

Error in (function (display = "", width, height, pointsize, gamma, bg,  : 
  X11 module cannot be loaded
In addition: Warning message:
In (function (display = "", width, height, pointsize, gamma, bg,  :
  unable to load shared object '/Library/Frameworks/R.framework/Resources/modules//R_X11.so':
  dlopen(/Library/Frameworks/R.framework/Resources/modules//R_X11.so, 6): Library not loaded: /usr/X11/lib/libSM.6.dylib
  Referenced from: /Library/Frameworks/R.framework/Resources/modules//R_X11.so
  Reason: image not found

How can I go about resolving this?

Solution

  • Execute the following in a terminal window:

    locate libSM.6.dylib

    or do it from an R console:

    system("locate libSM.6.dylib")

    On my Yosemite install it's in /opt/X11/lib/libSM.6.dylib.

    If your setup is similar, then:

    sudo ln -s /usr/X11 /opt/X11

    should help fix this temporarily, but I'd keep looking for a Yosemite R package (since that will accommodate all the changes Apple made to the filesystem structure).
