Things you might try:

1) delete your .RData file
2) delete your .Rhistory file  # both of these are hidden by default  
so you need to either do it from a Terminal session or change the  
defaults for display of system files in Finder
3) repair permissions (probably the easiest way is with Disk  
Utility.app)

In the past I have had problems with R freezing up when I attempted to  
access external links to pdf files from the help window when using the  
GUI, but I have not been able to reproduce that behavior consistently.  
If you can notice what you are doing just before the freeze, that  
might be helpful.
