How to refer to a list member by variable
Dear All,
I'm hoping one of you can help me with the following R problem. I'm
trying to refer to a member of a list by variable. However, this seems
not to work:
foo=list(first=c(1:10),second=c(11:20))
> foo$first
[1] 1 2 3 4 5 6 7 8 9 10
> foo$"first"
[1] 1 2 3 4 5 6 7 8 9 10
> goo=c("first")
> foo$goo
NULL
> foo$goo[1]
NULL

translating sas proc mixed to lme()
Hi All
I am trying to translate a proc mixed into a lme() syntax. It seems that I was
able to do it for part of the model, but a few things are still different.
It is a 2-level bivariate model (some call it a pseudo-3-level model).
PROC MIXED DATA=psdata.bivar COVTEST METHOD = ml;
CLASS cluster_ID individual_id variable_id ;
MODEL y = Dp Dq / SOLUTION NOINT;
RANDOM Dp Dq / SUBJECT = cluster_ID

problem with glm(family=binomial) when some levels have only 0 proportion values
Hello everybody
I want to compare the proportions of germinated seeds (seed batches of
size 10) of three plant types (1,2,3) with a glm with binomial data
(following the method in Crawley: Statistics,an introduction using R,
p.247).
The problem seems to be that in two plant types (2,3) all plants have
proportions = 0.
I give you my data and the model I'm running:

code optimization
I have a function "eval.delta" which does what I want but isn't very
elegant. I have consulted the R documents, MASS, and S Programming. Is
there a practical way to optimize the code? Thank you very much.

Function:
eval.delta <- function(delta){
cat("VALUES\n")
vlr <- NULL
k <- 0

Print several xyplots to the same page in a pdf file
Hello everybody,
I'm using the lattice package and the xyplot to make several graphs like below. However, I can just print the three grouped plots onto one page as I'm putting them into a pdf-file, which gives me a huge amount of pages... Is it possible to put them all, or at least more than one on the same page, for instance put three groups beside each other like columns?

Working Passwd Chat for Unix Password Sync on Redhat 6.1
I have been trying to get the password sync working for Redhat 6.1 (samba 2.05a
rpm). I got
the PDC working this morning, so I'm happy. The FAQ section on the samba site
was very
helpful. The password sync was the only sticking point.
The default passwd chat script didn't work well
passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n *passw
