I have just uploaded version 0.4 of my libraries to the CRAN site.
Hopefully, they will shortly become available.

New features include:

1. The generalization of the Wilkinson and Rogers notation (~) to
   nonlinear formulae containing unknown parameters (in a way similar
   to knowns and unknowns in Maple or Mathematica). These are
   incorporated into all 12 of my functions accepting nonlinear
   models. For example, the linear models,
	~x
	~a+b*x
   and
	mu <- function(p) p[1]+p[2]*x
   are equivalent, if x is available in the environment and a and b
   are not. A nonlinear model may now be written as, for example
	~a+b*exp(d*x)
   as well as in the previous way,
	mu <- function(p) p[1]+p[2]*exp(p[3]*x)
   Note that use of the W&R notation will be highly inefficient (in the
   S-Plus style of making multiple copies of the data) as compared to
   the formulae with unknown parameters or direct specification as an
   R function. However, the latter cannot contain factor variables and
   operators have a different meaning in the two types of formulae.
2. Specification of the environment in which the covariates are to be
   found: either the global environment or one of my repeated
   measurements data objects. This works both with formulae and with
   functions. Thus, in all the examples above, x might exist only
   inside a data object and would be found if that object were
   specified as the environment.
3. Various improvements to my objects for unbalanced repeated
   measurements, including handling of non-repeated measures, such as
   independent data, single time series, and spatial data.
4. A function for repeated measures ANOVA (called rmaov, in my growth
   library) contributed by Ralf Goertz.
5. Binomial distributions added to pbirth for modelling overdispersion
   by birth models.
6. Examples that work! However, many use randomly generated data, so
   that the functions may not converge and may produce NAs for the
   s.e.s because of poor initial estimates of the parameters.
7. Many minor changes to improve speed.
8. Bug corrections, including those submitted by various users, whom I
   thank.
See the changes.txt file in the rmutil directory for further details.

I strongly recommend that you only use these libraries with R0.64, if
   you wish to avoid core dumps.

These changes have been rather major and have certainly introduced
bugs. Please report them! Thanks!
Jim
