Is there an existing function to compute Cook-Weisberg confidence curves
for non-linear model parameters in R?

from a lot of trouble & time.

covariates in nlmer function
...Dioxide Uptake" example from p. 368 onwards in the PB200 book.
The model without fixed effects covariates runs well but how to tell
nlmer to include Type and Treatment similar to the nlme model on p. 374
in the PB2000 book? Or is this something that has not been implemented
yet?

Seeking optimal mixture
...g.
x1=0
x2=0.25
x3=0.75
produces 48.089 (but is not necessarily the maximum response).
I have looked at optim() and wondered if I could use it somehow to solve
my problem. However, I have not found a way to tell optim() about my sum
constraint x1+x2+x3=1. All help is appreciated.

location of Tisean executables when using RTisean and jumping between linux and windows
...estions are:
1) Is there a way I could break the link of the Tisean executables to
the linux location so that when run in windows the executables in
windows will be used?
2) Is the hard coding of the location of Tisean executables to the
workspace image deliberate and necessary?
Many thanks,

...-cran-vr, r-omegahat-ggobi, r-cran-kernsmooth none

What shall I do to get also these package to the package index?

gam predictions with negbin model
Hi,
I wonder if predict.gam is supposed to work with family=negbin()
definition? It seems to me that the values returned by type="response"
are far off the observed values. Here is an example output from the
negbin examples:
> set.seed(3)
> n<-400
> dat<-gamSim(1,n=n)
> g<-exp(dat$f/5)

merging data frames with matrix objects when missing cases
Hi,
I have faced a problem with the merge() function when trying to merge
two data frames that have a common index but the second one does not
have cases for all indexes in the first one. With usual variables R
fills in the missing cases with NA if all=T is requested. But if the
variable is a matrix R seems to insert NA only to the first column of
the matrix and fill in the rest of the columns by

logit and polytomous data
..."cheese taste\" example (5.3.1. p. 109) of
the book. I tried to analyse the cheese example with R but
failed to do so because R allowed me to use logit link
function only with binary family that supposes 0 <= y <= 1.
Do I need to scale the y\'s or is there another way?

Loading required package: grid

control=nls.control(minFactor=yy) option. Is there a way to get around
this or does this mean that my model is not estimable with R?

extract variables from linear model
Hi,
I fitted a linear model:
fit <- lm(y ~ a * b + c - 1 , na.action='na.omit')
Now I want to extract only the a * b effects with confidence intervals.
Of course, I can just add the coefficients by hand, but I think there
should an easier way.
I tried with predict.lm using the 'terms' argument, but I didn't manage
to do it.
Any hints are appreciated,
best,

error in display function of the ARM package
Hi,
I get the following error message when trying to use the display
function on the ARM package:
> display(model)
Error in .Internal(round(x, digits)) : no internal function "round"
Looks like some kind of mismatch between the ARM package and some
others? Can I somehow get around it? I have learned to like the display
function to print model summaries.

Matrix manipulation
Hi,
Suppose I have a matrix with, say 12 columns.
I would like to extract out column 2 ~ 8 and 11 ~ 12 then combine them together.
I tried with success to extract out the columns by doing:
foo <- test[,2:8]
goo <- test[,11:12]
However then I am having trouble combining foo and goo.
Helps are appreciated!
Cheers,
Kevin
