Re: [R] Tables: Invitation to make a collective package
If the functionality you are thinking of already exists across multiple
packages an alternative to creating a new package would be to create
a task view as in:
http://cran.r-project.org/src/contrib/Views/
as explained in the ctv package and the article in R News 5/1.

[R] Tables: Invitation to make a collective package
Hi All,
I would like to make an invitation to make a collective package with all
functions related to TABLES.
I know that there are many packages with these functions, the original idea is
collect all this functions and to make a single package, because is arduous for
the user know all this functions broadcast in many packages.
So, I think that the original packages can continue with its original
functions,

functions related to tables.
