R version 2.6.0 beta (2007-09-23 r42958)
it checks out fine but here:

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.

for writing programs as well.

You can do this:
aggregate(iris[-5], iris[5], mean)

Is there some way of displaying the expression and evaluation environment
associated with a promise? I have found the following:
# first run these two commands to set up example
e - new.env()
delayedAssign(y, x*x, assign.env = e)
# method 1. shows expression but not evaluation environment

a nuisance
and I hope this warning can be removed.

Also note that earlier in the same example we have:
msg - old

x #- new!

That is substitute(x) gives x, not msg.

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

You can define as.Date.numeric in your package and then it will work. zoo
has done that.
library(zoo)
as.Date(10)
This is also a nice idea. Although adding to a package is possible, it is
now very hard

A fourth approach would be the proto package. It provides a thin
layer over environments making use of the prototype (aka object-based)
style of programming which is fundamental different relative to
class-based programming (although it is powerful enough to encompass
class based programming).
