Version 1.1-0 of bayesm
Version 1.1-0 of bayesm is now available on CRAN.
This version includes Bayesian inference for the NBD(Poisson) regression
model and a hierarchical version of the same. It also includes an additional
dataset with count data and various covariates.
Comments and suggestions for improvement are most welcome.

package submission and binary versions
Dear r-help-
>From reading the CRAN web page, it appears that you should not submit
precompiled binary versions of your package, but rather that these
are built for you by someone working with CRAN. I submitted my
package using R CMD build but without the binary flag on. I'd like
to have a binary version available for Windows users. Should I submit
a precompiled binary version as well?

advice on crafting examples for packages
Folks-
I have developed a package which I am planning on posting to CRAN.
I include examples for each of the 40 or so functions in the package.
However, since the examples are non-trivial and the package is
using MCMC simulation methods, it takes about 20 minutes to run the complete
set of examples on a 2.8 Ghz windows PC. The R process reaches a high
water mark of about 100 MB of memory as

release of version 2.0-1 of bayesm
Folks-
We are pleased to announce the release of version 2.0-1 of bayesm.
Highlights of the new version:
1. Bayesian treatment of SUR (seemingly unrelated regression)
2. Added clustering to mixture of normals models
3. Added routines to compute implied univ and bivariate densities from
mixture of normals MCMC draws
4. improved input error checking in many routines

bayesm version 2.2-0
bayesm version 2.2-0 is now available on CRAN.
Major changes include:
1. general density estimation using a Dirichlet Process Prior and a
normal base
2. linear instrumental variable models with unknown error distributions
(the Bayesian analogue of IV methods). Achieved via DP priors.

Check errors using R2.6.2
I can successfully "check" a package with source under 2.5.1, including
compiling source files and running examples with no errors or warnings.
when I try with R2.6.2, I get make errors:
making bayesmc.d from bayesmc.c
make[3]:gcc-sjlj: Command not found
etc.
my gcc is version 3.4.2
I'm using Windows XP.
Any thoughts?
thanks!

S3 vs S4 classes
I have developed a package, bayesm, which uses existing classes of
objects. I would like
to add a new class corresponding to objects from this package.
I have been reading about classes and all sources tell me that I should
use
so-called "new" or S4 classes.
However, a major purpose of defining a class for my package would be to
add methods to the existing generic functions: print,

vectorization of groups of dot products
I have a set of n vectors, x_1, ..., x_n, of the same length.
I would like to form the vector of dot products -- x_1'x_1, ..., x_n'x_n
the fastest way I can think to do this is to put the vectors into a
matrix
and do
diag(crossprod(X))
however, this seems to be very wasteful since this computes n(n+1)/2-n
unnecessary
dot products.
Is there a better way using existing functions in R?

.Call question
Writing R Ext says to treat R objects that are arguments to .Call as
read only (i.e. don't modify).
I have a long list of lists that and I want to avoid the overhead of a
copy in my C code. I would just like to modify some of the elements
of list by replacing them with elements of exactly the same size/type.
below is an example of the essence of the problem. This seems to work.
Is this

run-time of an R function
I have noticed dramatic differences in the run-time for the execution of
one of my functions depending on whether or not R was restarted.
Immediately
after restart of R GUI, exec time = 2.8 min. If I then repeat the
execution
of the function in the same R session, exec time = 7.1 min. Removing all
objects via rm(list=(all=TRUE)) and initiating gc (gc(reset=TRUE))
helps, but
only slightly (exec

optimization with Sparse matrices
To whom it may concern,
I am trying to maximize a log-likelihood function using optim. This is a simple problem with only 18 parameters. To conserve memory, I am using sparse matrices (SLAM) for some of the data matrices used in the computation of the likelihood. However, optim appears to convert the sparse matrix back to regular data format. This causes me to run out of memory as R tries to

3d polar coordinates in rgl function view3d()
Dear all:
I'm enjoying using rgl and I want to set a specific viewpoint.
I understand that view3d() will do so by setting the 3d polar
coordinate angles, theta and phi.
In standard polar coordinates, theta is the angle away from the X axis
in the X-Y plane and phi (inclination angle) is the angle between the
Z axis and the radius vector
It appears that when you use view3d() theta is
