r - OS X Yosemite 升级后无法在 R 中加载 X11

Question

升级到 Yosemite 后，当我尝试使用 ggplot2 并在控制台中绘图时，遇到以下错误:

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

我该如何解决这个问题？

Answer 1

操作系统更新似乎删除了/usr/X11 和/usr/X11R6 符号链接(symbolic link)。请从 http://xquartz.macosforge.org 重新安装 XQuartz这将为您再次设置符号链接(symbolic link)。
