Look in the R > Preferences >Startup dialog under the "Initial working  
directory" section. You'll see you can run this from the command line  
in order to open R.app within a given directory:

$ open -a R.app <dir-or-file>

So, to open in the current directory, just type:

$ open -a R.app .

You can make an alias for this and set it in your .bash_profile in  
order to make your life easier, maybe:

alias r="open -a R.app ."

Small r so it doesn't interfere with /usr/bin/R

Hope that helps,
