Fortunately not.  SAS is one of the few large systems that does not 
implicitly support value labels and that separates label information 
from the database [I can't count the number of times someone has sent me 
a SAS dataset and forgotten to send the PROC FORMAT value labels].  See 
the factor function for information about how R does this.
