Well, the assumption seems to be that end users who just run an  
installer without reading the associated documentation won't be  
interested in a command-line version and will just start the R GUI  
that shows up in their /Applications folder ...

... and that people who add directories to their PATH tend to read  
instructions carefully.  The download page for the Mac OS X binaries

and in the Mac OS X FAQ you'll easily find the necessary instructions  
for using the command-line version:

I suppose that with "doing things the Unix way" you've probably been  
referring to the package managers / installers that most Linux  
distributions use and which do indeed make their installed programs  
available from the command line.
