I actually figured this one out just now.  If creating a file in a 'stand alone' 
code block, the default directory is the directory that the org file itself is 
in.  However, in a 'session' code block, the default directory is something else 
(R's default?).  If I specify the full path to the file in the 'session' code 
block, things work better.

Sorry for the noise!
