Hi ,

  I don't know whether it is a Mac specific problem. I hope it does  
not bother you.

When I start R each time I got the following warning , I reinstall for  
many times the problem still exists.

  R(4053,0xa0619fa0) malloc: *** error for object 0x15630350: double  
free
*** set a breakpoint in malloc_error_break to debug
R(4053,0xa0619fa0) malloc: *** error for object 0x15630f10: double free
*** set a breakpoint in malloc_error_break to debug
