package dependency error on loading lme4
Hi all,
I recently (today) updated the Matrix package and installed the latticeExtra
package, but then when I tried to load the lme4 package, I got the following

S4 Generics and NAMESPACE : justified warning ?
Dear list,
It seems that a package (pkgB) using another package (pkgA) with S4
generics formed by taking existing functions (for example 'plot') must
not import the existing functions ('plot') in its namespace to avoid
the warning "replacing previous import: plot".
Suppose we use the simple 'import' directive in the name space of
pkgB.

numeric coercion when one or more elements is non numerice
I don't understand this behavior. Why does the every data point get trashed by data.matrix when there is one non-numeric element in the array? Thanks.

Possible problem with namespaceImportFrom() and methods for generic primitive functions
Hi all,
I have a problem with a package that imports two other packages which both
export a method for the `[` primitive function.
I set up a reproducible example here:
https://github.com/kforner/namespaceImportFrom_problem.git
Basically, the testPrimitiveImport package imports testPrimitiveExport1 and
testPrimitiveExport2, which both export a S4 class and a `[` method for the
class.
Then:

evaluation of expressions
Hi, all. I'm trying to automate some regression operations in R but am
confused about how to evaluate expressoins that are expressed as
character strings. For example:
y <- ifelse (rnorm(10)>0, 1, 0)
sex <- rnorm(10)
age <- rnorm(10)
test <- as.data.frame (cbind (y, sex, age))
# this works fine:
glm (y ~ sex + I(age^2), data=test, family=binomial(link="logit"),

student-t regression in R?
Is there a quick way to fit student-t regressions (that is, a regression
with t-distributed error, ideally with the degrees-of-freedom parameter
estimated from the data)? I can do it easily enough in Bugs, or I can
program the log-likelihood in R and optimize using optim(), but an R
version (if it's already been written by somebody) would be convenient,
especially for teaching purposes.

pulling items out of a lm() call
I want to write a function to standardize regression predictors, which
will require me to do some character-string manipulation to parse the
variables in a call to lm() or glm().
For example, consider the call
lm (y ~ female + I(age^2) + female:black + (age + education)*female).
I want to be able to parse this to pick out the input variables

lmer(): nested and non-nested factors in logistic regression
Thanks to some help by Doug Bates (and the updated version of the Matrix
package), I've refined my question about fitting nested and non-nested
factors in lmer(). I can get it to work in linear regression but it
crashes in logistic regression. Here's my example:
# set up the predictors
n.age <- 4
n.edu <- 4
n.rep <- 100
n.state <- 50
n <- n.age*n.edu*n.rep

Can lmer() fit a multilevel model embedded in a regression?
I would like to fit a hierarchical regression model from Witte et al.
(1994; see reference below). It's a logistic regression of a health
outcome on quntities of food intake; the linear predictor has the form,
X*beta + W*gamma,
where X is a matrix of consumption of 82 foods (i.e., the rows of X
represent people in the study, the columns represent different foods,
and X_ij is the amount of

another question about lmer, this time involving coef()
I'm having another problem with lmer(), this time something simpler (I
think) involving the coef() function for a model with varying
coefficients. Here's the R code. It's a simple model with 2
observations per group and 10 groups:
# set up the predictors
n.groups <- 10
n.reps <- 2
n <- n.groups*n.reps
group.id <- rep (1:n.groups, each=n.reps)

mcmcsamp shortening variable names; how can i turn this feature off?
I have written a function called mcsamp() that is a wrapper that runs
mcmcsamp() and automatically monitors convergence and structures the
inferences into vectors and arrays as appropriate.
But I have run into a very little problem, which is that mcmcsamp()
shortens the variable names. For example:
> set.seed (1)
> group <- rep (1:5,10)
> a <- rnorm (5,-3,3)

yet another lmer question
I've been trying to keep track with lmer, and now I have a couple of
questions with the latest version of Matrix (0.995-4). I fit 2 very
similar models, and the results are severely rounded in one case and
rounded not at all in the other.

> group <- rep (c(1,2), c(5,5))
> M1 <- lmer (y ~ 1 + (1 | group))

lmer with nested/nonnested groupings?
I'm trying to figure out how to use lmer to fit models with factors that
have some nesting and some non-nested groupings. For example, in this
paper:
http://www.stat.columbia.edu/~gelman/research/published/parkgelmanbafumi.pdf
we have a logistic regression of survey respondents' political
preferences (1=Republican, 0=Democrat), regressing on sex, ethnicity,

trying to use standard notation
Hi, all. In setting up my package for post-processing regression
models, I am trying to use standard notation as much as possible: thus,
I use coef() to access estimated coefficients. I wrote a function
called se.coef() to grab standard errors, and se.fixef() and se.ranef()
to grab se's from coefficients estimated from lmer().
I also need a function to access sigma-hat (the residual sd

Bayesian logistic regression?
Hi all.
Are there any R functions around that do quick logistic regression with
a Gaussian prior distribution on the coefficients? I just want
posterior mode, not MCMC. (I'm using it as a step within an iterative
imputation algorithm.) This isn't hard to do: each step of a glm
iteration simply linearizes the derivative of the log-likelihood, and,
at this point, essentially no
