norm package prelim.norm
Hey eveyone! I hope someone can help wiht this question. I have a matirux of all zeros and ones and I would like to indentify all unique patterns in the rows andthe number of times the pattern occurs. I changed all zeros to NA tried to use prelim.norm to identify all patterns of missing data in the rows. I got the message

goodfit par estimates
Hey,
Does anyone know if there is a way to get back from goodfit what it estimated the parameters to be?
I used the code
fit<-goodfit(round(data$PLX_NRX),type="nbinomial"
and got a pretty good fit. I could not however duplicate this good fit with any parameter estimates that I had.
Any ideas???
Thanks,
Elizabeth Lawson

partially linear models
Hey,
I am estiamting a partially linear model y=X\beta+f(\theta) where the f(\theta) is estiamted using wavelets.
Has anyone heard of methods to test if the betas are significant or to address model fit?
Thanks for any thoughts or comments.

.C help
Hi,
I am hoping some one can help me. I am learning to use C and would like to learn how to call c code in R. I have look at
Writing R Extensions
and I tried to copy the example on page 38

{
int i, j, nab = *na + *nb - 1;

linking C and R
hey,
I am running R 2.0.1 on a the terminal of my MAC OS X and I have written some C code that I would like to use dynload to bring into R. When I try to compile the code i get the error R.defines.h no such file or directory. I know that the file is in resources/include but where do I have to move the file to so that the compiler can access it? I tried copying Rdefines.h and R_ext folders

nlme Singularity in backsolve at level 0, block 1
Hi,
I am hoping some one can help with this.
I am using nlme to fit a random coefficients model. It ran for hours before returning

The model is

differnce between lme and proc mixed
Hey,
I was using lme and proc mixed in SAS to run a empirical bayesian model.
I used the same method for both lme and proc mixed (the default REML).
I got very similar, but not identical results. I am just wondering if anyone knows what the differneces may be between proc mixed and lme.
Any thoughts would be appreciated!
Thanks,

any WINEDLLPATH caveats I should know about?
Hi,
I am attempting to run the libiconv test-suite using wine and one of
the problems I am having is that the executables are not able to find
the DLL, even when setting WINEDLLPATH, as in:
WINEDLLPATH=../lib/.libs wine .libs/table-to
Am I doing something wrong?
Thank you,

Fwd: Re: Wavelet reconstruction
I realized that I may not have answered the question you were asking and that no one else has responded. I can across a similar problem and may have an answer to your question now. If you have both the wavelet coefficients and the scaling coefficients then create a fake sequence of the same length as the original and decompose that sequence using wd form wavethersh with the same wavelet family

segmetation fault
Hey,
I don;t know if anyone has come across this error before...
I am running R on the terminal of my MAC OS X 10.3.4 and I have written C code and compiled it using
R CMD SHLIB mycode.c
There were no problems in compiling so I now have mycode.o and mycode.so.
I used dyn.load("mycode.so") and again, no problems. But when I try to use the code .C("mycode",x)

Griddy-Gibbs sampler
Hey everyone,
I have read the paper by Ritter and Tanner(1992) on Griddy-Gibbs sampler and I am trying to implement it in R without much luck. I was wondering if anyone had used this or could point me to any example code.

Filters in waveslim
Dear R Users,
For running wavelet functions using dwt( ), modwt( ), and mra( ), a wavelet filter algorithm is applied. For all these functions, default is "la8" and other possibility is "haar". In related documents, another possibilities like as symlet and coiflet ... are not cited.
Besides "la8" and "haar", which wavelet filters can be used?
Thank

mixed effects models - negative binomial family?
Hello all,
I would like to fit a mixed effects model, but my response is of the
negative binomial (or overdispersed poisson) family. The only (?)
package that looks like it can do this is glmm.ADMB (but it cannot
run on Mac OS X - please correct me if I am wrong!) [1]
I think that glmmML {glmmML}, lmer {Matrix}, and glmmPQL {MASS} do
not provide this "family" (i.e. nbinom, or
