R help - Oct 2010 - read.spss warning message (Unrecognized record type 7, subtype 18 encountered in system file)

Hello Everyone,
 
Trying to help someone recover the contents of an SPSS.sav file using read.spss.
This seemed to work well but produced a warning message. My code and the warning
are displayed below.
 
Spent some time looking for previous questions about this warning. Found a lot
of questions posted but wasn't able to figure out what the problem is.
 
Is there anyone out there who can explain what's going wrong and how I can
fix it?
 
Thanks,
 
Paul

If you do a search of the archives you will find several similar  
questions. As far as I know the answer has generally been unavailable.  
It is after all only a warning and you should have gotten uesful  
material in the returned value.

Record 7 is an extension record for the SPSS sav file format.  It is used for
new features in order to preserve the ability of older versions of SPSS to
read newer files.  I don't recall what subtype 18 is, but in most cases, an
unrecognized subtype does not affect the data.
