I agree that wider use of generics in the core of R is desirable as
it facilitates designs in various addon packages that are much easier

The generics don't have to be S4. In fact, in many cases it would
be better to have them be S3 for consistency with other similar generics
in the core of R.
Or I wonder about the possibility of having generics which can have
some methods being of S3 and others of S4.

I suggest you define a "relist" class and then define an unlist
method for it which stores the skeleton as an attribute. Then
one would not have to specify skeleton in the relist command
so
relist(unlist(relist(x))) === x
1. relist(x) is the same as x except it gets an additional class "relist".
e added to unlist.

If integrate is changed it would be nice at the same time to make it

is not. Ryacas provides a deriv method but for integrate Ryacas inconsistently
provides Integrate since integrate is not generic.

On Windows Vista hhc.exe is not available. One can do this on an
install:
rcmd install --docs=normal myPackage
to avoid the message about hhc.exe; however,
"rcmd build" does not appear to support --docs=normal so one cannot
do a build without getting a message about hhc.exe (although the build

rid of the message or improve the message.
Again, this all refers to doing a build on Vista.

1. Is there some way to copy a promise so that the copy has the same
expression in its promise as the original. In the following we
y is a promise that we want to copy to z. We
want z to be a promise based on the expression x since y is a
promise based on the expression x. Thus the answer to the
level of warnings that issue
information on garbage collection, closed connections, etc. or perhaps the
user could have control over it but having it as the default is really
a nuisance
and I hope this warning can be removed.

Is there some way of displaying the expression and evaluation environment
associated with a promise? I have found the following:

I noticed that R 2.7.0 will have as.Date.numeric with a second
non-optional origin argument. Frankly I would prefer that it default
to the Epoch since its a nuisance to specify but at the very least
I think that .Epoch should be provided as a builtin variable.
When I do
Rcmd check Ryacas
on my Windows Vista system under
R version 2.6.0 beta (2007-09-23 r42958)
it checks out fine but here:
http://cran.r-project.org/bin/windows/contrib/checkSummaryWin.html
http://cran.r-project.org/bin/windows/contrib/2.5/check/Ryacas-check.log
it complains

Consider a package that this DESCRIPTION file:

Package: tester
Version: 0.1-0
Date: 2007-10-12
Title: Prototype object-based programming
Author: Gabor Grothendieck
Maintainer: Gabor Grothendieck <[EMAIL PROTECTED]>
Description: test
LazyLoad: true
Depends: R (>= 2.6.0)

If you are modifying it it would also be nice to add
{ to the derivative table so one can write this:
f <- function(x) x*x
deriv(body(f), "x", func = TRUE)
Currently, one must do:
deriv(body(f)[[2]], "x", func = TRUE)
