[R-SIG-Finance] error in loading rugarch package

[Donglei Du]

Dear all, 

I resolved the problem by installing XQuartz  http://xquartz.macosforge.org <http://xquartz.macosforge.org/>, since X11 is no longer included with OS X.

Since the problem is resolved before I received the suggestion of installing rgl package from CRAN, I do not know if these two solutions serve the same purpose. 

Thanks
