What we really need is a latex method for contents.  As I usually 
include latex(describe(mydata), file='') in an Sweave report I haven't 
needed this.  If any others need it I'll probably write 
latex.contents.data.frame.  In the meantime you can take the object 
produced by contents( ) and remove the value levels components, then 
pass the smaller object to latex().
