R can not show plots (in Mac OS X terminal)

Hi,
You should use X11. It doesn't work in Terminal.
You can use the basic Xterm in X11 or like I do Aterm.

This is not actually true.  It does work in Terminal, you just have to 
specify the DISPLAY, either in the shell before entering R
%  setenv DISPLAY :0
or when you call x11()

 x11(display=":0")
