[R] html/rtf formatted output

[Vikas Rawal]

I would like to tabulate summaries of data generated using aggregate
function.  The task needs to be done in two steps. 

First, reshape a data frame (or output of aggregate function) into a
desirable form. This could typically have multiple levels of column
and row headers, numbers in the cells.

Secondly, parse this through something that will give html/rtf
formatted output.

Does anyone know how to do this?
