[R] Curious warning in R for OS X w/Xwindows

[Bear F. Braumoeller]

I recently reformatted my TiBook and reinstalled everything from the 
system up.  After installing Apple's version of XWindows and the 
XWindows version of R 1.7.0, I ran the two and got a strange warning:

-----

Type `q()' to quit R.

 > help("lm")
WARNING: terminal is not fully functional
-  (press RETURN)
-----

The main functional disabilities I've noticed after I press return are 
more or less cosmetic -- the arrow keys don't scroll, for example; 
rather, they produce ugly characters on the screen -- but are 
nevertheless annoying.  Moreover, I don't get this message in a regular 
terminal window when I use the "man" command; there, the viewer works 
exactly as it should.

Has anyone else encountered this, and does anyone have a fix?


Thanks,
-Bear
