something wrong when using pspline in clogit?
Dear R users:
I am not entirely convinced that clogit gives me the correct result when I
use pspline() and maybe you could help correct me here.
When I add a constant to my covariate I expect only the intercept to change,
but not the coefficients. This is true (in clogit) when I assume a linear in
the logit model, but the same does not happen when I use pspline().
If I did something similar

Rms package - problems with fit.mult.impute
Hi!
Does anyone know how to do the test for goodness of fit of a logistic model (in rms package) after running fit.mult.impute?
I am using the rms and Hmisc packages to do a multiple imputation followed by a logistic regression model using lrm.
Everything works fine until I try to run the test for goodness of fit: residuals(type=c("gof"))
One needs to specify y=T and x=T in the fit. But

tapply and more than one function, with different arguments
Dear R-users,
I am working with R version 2.10.1.
Say I have is a simple function like this:

Now, I want to apply this function along with some other (say 'max') to a simple data.frame, like:

Formula evaluation, environments and attached packages
Hi!
Some time ago, I replaced calls to library() with calls to
requireNamespace() in my package logmult, in order to follow the new
CRAN policies. But I just noticed it broke jackknife/bootstrap using
several workers via package parallel.
The reason is that I'm running model replicates on the workers, and the
formula includes non-standard terms like Mult() which are provided by
gnm. If gnm

[SCEV] getMulExpr could be extremely slow when creating SCEVs for a long chain of add/mul instructions
Hi,
I'm working on a slow-compile problem caused by SCEV (PR28830), and I need your suggestions on how to fix it. The loop below causes ScalarEvolution::getMulExpr to hang.
int get(unsigned n)
{
unsigned i, j, mult = 1;
for (i = 0; i < 1; i++) {
for (j = 0; j < 30; j++) {
mult *= n++;
}
}
return mult;

mult.fig() utility [was "margin text mtext"]
Martin,
I have an objection in principle to anything that has the side-effect of
clobbering something in the global environment, even something as innocuous
looking as "old.par". I certainly object to putting something like that
into a public library, however clever and useful the code might be. It just
is not safe.
As a quick way round this I suggest the following (R only) solution:

multcomp
I used the multcomp package sometime back for doing multiple
comparisons. I see that it has been updated and the methods like simint
are no longer supported. When I run the program it prompts to me to use
glht. How do I get the lower and upper conf int and the pValues using
glht? Does anyone have an example?
Thanks ../Murli

fit.mult.impute and quantile regression
I have a largish dataset (1025) with around .15 of the data missing at random overall, but more like .25 in the dependent variable. I am interested in modelling the data using quantile regression, but do not know how to do this with multiply imputed data (which is what the dataset seems to need). The original plan was to use qr (or whatever) from the quantreg package as the 'fitter'

Error message in fit.mult.impute (Hmisc package)
Hello,
I would like to use the aregImpute and fit.mult.impute to impute missing
values for my dataset and then conduct logistic regression analyses on the
data, taking into account that we imputed values. I have no problems
imputing the values using aregImpute, but I am getting an error at the
fit.mult.impute stage.

multiple imputation with fit.mult.impute in Hmisc
I have always avoided missing data by keeping my distance from

real patients. We're trying to test regression models using
multiple imputation. We did the following (roughly):

fit.mult.impute() in Hmisc
I tried multiple imputation with aregImpute() and

The warning message below suggests that summary(f) of
fit.mult.impute() would only use the last imputed data set.
Thus, the whole imputation process is ignored.

I have a problem using the function call tracing tools that is designed in llvm tools set. My aim is to record every function call that a program makes when it run.

[LLVMdev] [PATCH] mult-alt tests
The enclosed zip has some test files for both LLVM and Clang, to go along
with the last mult-alt patch I submitted to the list.
You'll note that some of the code is commented out for various problems not
directly related to the mult-alt stuff.
Though I worked on some additional versions for platforms not included here
in the LLVM tests, they have various problems with the lowering, but which

Formula evaluation, environments and attached packages
Hi Milan,
I expect I may be able to do something about the way the terms are
evaluated, to ensure the evaluation is done in the gnm namespace (while
still ensuring the variables can be found!).
In the meantime, I think the following will work:
Mult <- gnm::Mult
f <- Freq ~ Eye + Hair + Mult(Eye, Hair)
gnm::gnm(f, family=poisson, data=dat)
Hope that helps,
