Helloe dear Duncan, Gabor, Michael and others,
After taking some time, I wrote a bridge function between a "cast_df"
object from the {reshape} package into a table in Duncan's new {tables}
package.
The motivation was to make "cast_df" table prettier in the R terminal, as
well as allow us to export a pretty version of the table to latex (using
Hmisc::latex, on the output of tabular.cast_df)
The code is now available on:

I would be happy for any input/revisions/suggestions from you.
Seems like a nice idea. Two comments:
1. I did add a Factor() function as described in the message you quote
from me, so you might be able to use that and simplify things a little.
2. It's more flexible to construct the language object as a language
object, rather than pasting something together and parsing it. For one
thing, that allows non-syntactic variable names; I think it's also
easier to read. So your code
txt<- paste("tabular(value*v*", LEFT , "~" ,RIGHT ,", data = m_xx, suppressLabels =
2,...)", sep = "")
eval(parse(text = txt ))
could be rewritten as
formula<- substitute( value*v*LEFT ~ RIGHT, list(LEFT=LEFT, RIGHT=RIGHT))
tabular(formula, data = m_xx, suppressLabels = 2, ...)
It might make sense to put something like this into the tables package, but I
don't want to have a dependency on reshape.
