Try:
censummary(AsExample$AsLow, AsExample$AsHigh, AsExample$AsCen)
From the Introduction to R (http://cran.r-project.org/doc/manuals/R-
intro.html#Lists-and-data-frames):
"Components of lists may also be named, and in this case the
component may be referred to either by giving the component name as a
character string in place of the number in double square brackets,
or, more conveniently, by giving an expression of the form
> name$component_name"
The same goes for data.frames.
