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().
