Yes, and it is included in the R release disk image (dmg) from CRAN,  
but it is optional, so you have to choose "custom install" and select  
it. You can also find the separate "tcltk" installer in the  
"Packages" directory of the image. Don't forget that this is X11 Tcl/ 
Tk, so you also have to install Apple's X11 and have it running.
