The documentation for ts says "Only one of ‘frequency’ or ‘deltat’ should
be provided" but why doesn't it enforce this with
stopifnot(missing(frequency) || missing(deltat))
Wouldn't that work? Also the documentation does not say what valid
time series parameters are. To find that out one mu

As a suggestion, it would be nice if the accessors() method could be
used to create just "getters" or just "setters" for particular fields,

You need to update your version of R (r-devel or 2.12 patched) to rev
53385 or later, and read NEWS, particularly the line:
- Assignment of an environment to functions or as an attribute to other
objects now works for subclasses of "environment".

Yet another inconsistency. environment<- does not work with S4:

Error in environment(tf) <- env :

Dear all,
First, many thanks to John Chambers, and anyone else who was involved,
for the new support for "reference classes" in R 2.12.0. It's nice to
see this kind of functionality appear in a relatively R-like form, and
with the blessing of the core team. In some contexts it is undoubtedly

You may want t
Hello all.
I'm developing a package for R holding a Gibbs sampler, which tends to have
better performance when written in C than in R.
During each iteration in the Gibbs sampler, I need the inverse of a
symmetric matrix.
For this, I wish to use lapack, as is concisely suggested in "Writing R
