Glimmix and glm
Hello.
Some months age an e-mail was posted in which a comparison between Glimmix
and glm was discussed. I have not been able to find that e-mail on the R
archive. Does anyone recall the date of the above e-mail?
Thank you very much.

Optim and likelihood computations
Hello everyone.
I want to write some likelihood functions to use with optim. For example
AR-structures, I have written a couple of functions that appear to get the
job done. But, since I am new to R, I wanted to ask if there are any
references in this topic.
Thanks in advance,

From 2.2.1 to 2.3
Hello everyone.
Currently I am running R 2.2.1 (windows), and I will like to update to
2.3. I wanted to ask if it is possible to update without having to removed
2.2.1; or do I first need to delete 2.2.1?
Thank you very much.

topTable function from LIMMA
Dear R-Help,
I am using the function "topTable" from the LIMMA package. To estimate
adjusted P-values there are several options (adjust="fdr" , adjust="BH")
as shown below:
topTable(fit, number = 10, adjust = "BH", fit$Name)
I guess any of these options (fdr, BH, etc.) is using a default of
FDR=0.05 which is quite conservative (i.e., very

nlme package
In using the NLME package (R 2.6.1 for Windows), I am having a problem in running an R script that used to run with no problems using a Linux OS in 2004. So I am wondering if during these last ~3 yrs we had major changes in the syntax of the NLME package that I am not aware.
This is the R script:
library(nlme)
treat=as.factor(c(1,2,1,2,1,2,1,2))
mouse=as.factor(c(1,1,2,2,3,3,4,4))

Newbie question
If I have 3 columns of data, col 1 = Independent Var; cols 2 and 3 are Dep.
Vars. I would like to produce a plot with both: col2=f(col1) and
col3=f(col1). How do I do this such that I can control line parameters
(line type, color, etc). I know that if I stack the data and col2 and col3
are treated as different factor levels, that I can accomplish this, but lose
control over the line

variables in object names
Is there any way to put an argument into an object name. For example,
say I have 5 objects, model1, model2, model3, model4 and model5.
I would like to make a vector of the r.squares from each model by code
such as this:
rsq <- summary(model1)$r.squared
for(i in 2:5){
rsq <- c(rsq, summary(model%i%)$r.squared)
}
So I assign the first value to rsq then cycle through models 2 through
