[Rd] Update today broke foreign package (PR#13533)

[rubin at msu.edu]

Hi,

I'm running R 2.8.1 on Ubuntu, and today I got updates for a couple of 
packages, including foreign (r-cran-foreign, now at version 0.8.32).  
Subsequent to the upgrade, attempts to invoke read.spss produce the 
following error:

Error in inherits(x, "factor") : object "cp" not found

and the call to read.spss fails.  I forced a downgrade to 0.8.26, and 
read.spss works again.

Cheers,
Paul Rubin
