A problem with jointprior (Deal package)
Greetings all,
I am trying to use Deal to learn a Bayesian Network for discrete data. I
came across the following problem with jointprior function.
>library(deal)
> a <- read.csv("prepared.cluster1.csv")
> fit <- network(a)
> fit.prior <- jointprior(fit)
Error in array(1, Dim) : 'dim' specifies too large an array

[Q] Bayeisan Network with the "deal" package
Dear R-users
I am looking for a help in using the "deal" package.
I followed the manual and paper from the author's web site to learn it, as
shown below, but I could not figure out how to access the local and
posterior probability of the nodes in the constructed network.

poisson mean hypothesis
Dear R-users,
Is there a way to get p-values for a one-sided hypothesis test about a
poisson mean?
Thanks,

New package for grouped data models
Dear R-users,
We'd like to announce the release of our new package "grouped"
(available from CRAN), for fitting models for grouped or coarse data,
under the Coarsened At Random assumption. This is useful in cases
where the true response variable is known only up to an interval in
which it lies. Features of the package include: power calculations for
two-group comparisons,

Change labels of x-axes in Plot of stl() function?
Hi all,
How can the label of the x-axes in the plot() of a stl.object be adapted?
e.g.,
When plotting: plot(stl(nottem, "per"))
In the labels of the x-axes is “time”. How can this be changed to e.g.,
“Time (dekade) “?
It does not work with xlab or others anymore…
Thanks,
Jan

Maximum likelihood estimate of bivariate vonmises-weibulldistribution
Thanks Dimitris!!! That's much clearer now. Still have a lot of work to
do this weekend to understand every bit but your code will prove very
useful.
Cheers,

survreg() with frailty
Dear R-users,
I have noticed small discrepencies in the reported estimate of the
variance of the frailty by the print method for survreg() and the
'theta' component included in the object fit:
# Examples in R-2.6.2 for Windows
library(survival) # version 2.34-1 (2008-03-31)
# discrepancy
fit1 <- survreg(Surv(time, status) ~ rx + frailty(litter), rats)

Bootstrapping stepAIC() with glm.nb()
Dear all,
I would like to Boostrap the stepAIC() procedure from package MASS for
variety of model objects, i.e.,

n <- nrow(data)
res <- vector(mode = "list", length = B)
index <- sample(n, n * B, replace = TRUE)
dim(index) <- c(n, B)

sharing word files
hello
I'm having the following problem:
On a share I have a user with read-only access to word files. Another
user has read-write access to these files.
When the user with read-only access opens a word file and then the
user with read-write access to these files opens the file, the
read-write user has only read-only access.
If the read-write user opens the word file first, then he has

'...' passed to both plot() and legend()
Dear R-devels,
I'd like to create a plot method for a class of objects that passes
the '...' argument to both plot() and legend(), e.g.,
x <- list(data = rnorm(1000))
class(x) <- "foo"
plot.foo <- function(x, legend = FALSE, cx = "topright", cy = NULL,
...){
dx <- sort(x$data)
plot(dx, dnorm(dx), type = "l", ...)

New Package 'JM' for the Joint Modelling of Longitudinal and Survival Data
Dear R-users,
I'd like to announce the release of the new package JM (JM_0.1-0
available from CRAN) for the joint modelling of longitudinal and
time-to-event data.
The package has a single model-fitting function called jointModel(),
which accepts as main arguments a linear mixed effects object fit
returned by function lme() of package nlme, and a survival object fit
returned by either

Effect display of proportional odds model
Dear useRs,
I very much like the effect display of the proportional odds model on
page 29 (Figure 8) of the following paper by John Fox:
http://socserv.mcmaster.ca/jfox/Papers/logit-effect-displays.pdf
It really gives a very concise overview of the model. I would like to
use it to illustrate the proportional odds mixed models we fit here for
a project on Diabetes but I can't seem to reproduce

fix variance parameter values for lmer estimation
Dear list-members,
a model is fit with lmer, but I want to force the variance parameter values
to be as defined by me
I thought, use 'start' to specify initial values and only allow for one
iteration ?
my question is how to do that ?
to specify the 2x2 matrix of variance parameter values:
start=list(groups=array(2,-0.5,1),dim=c(2,2))
now I need to make sure the mean structure is

package 'ltm' -- version: 0.3-0
Dear R users,
I'd like to announce the new version of the package "ltm" (available
from CRAN), for fitting Latent Trait Models (including the Rasch and
two-parameter logistic models) under the Item Response Theory
approach. Three main extra features have been added: (i) now both
ltm() and rasch() permit general fixed-value constraints (e.g., useful
for scaling purposes), (ii)
