p values for a GEE model
Hi all,
I have a dataset in which the output Y is observed on two groups of
patients (treatment factor T with 2 levels).
Every subject in each group is observed three times (not time points but
just technical replication).
I am interested in estimating the treatment effect and take into account
the fact that I have repeated measurements for every subject.
If I do this with repeated measures

pnorm how to decide lower-tail true or false
Hi to all,
maybe the last question was not clear enough.
I did not found any hints how to decide whether it should use lower.tail
or not.
As it is an extra R-feature ( written in
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/66250.html )
I do not find anything about it in any statistical books of me.

ks.test "greater" and "less"
Hello r-group
I have a question to the ks.test.
I would expect different values for less and greater between data1 and
data2.
Does anybody could explain my point of misunderstanding the function?
data1<-c(8,12,43,70)
data2<- c(70,43,12,8)
ks.test(data1,"pnorm")
ks.test(data1,"pnorm",alternative ="less") #expected < 0.001

Surprise when mapping matrix to image
Hello,
I wonder if
image(t(x)[ncol(x):1, ])
can do the job correct!
perhaps this does the job better:
image(t(x)[,nrow(x):1])

Message flags
How do I set message flags in sieve rules in such a way that e.g.
Thunderbird is displaying the mail as "important"? Is there a list of
hwo flags are interpreted by different IMAP clients?

Coercing a list to integer?
Dear group,
I am nearly beside myself. After an entire night spent on a niggling little detail, I am no closer to to the truth. I loaded an Excel file in .csv form into R. It apparentely loads as a list, but not the kind of list you can use. Oh no, it converts into a list that cannot be converted into an integer, numeric, or vector, only a matrix, whihc is useless without integers.

names of objects in .rda
Hi everyone,
sorry if this was discussed before (and in this situation, could you
please point me to the discussion in the archive? My search didn't
seem to be effective).
Is there a way of getting the names of objects in a .rda file without
having to load it?
Thank you very much,

writing function with ,... )
Hi to all
I did not found the right hints for functions with the dot-dot-dot argument.
Is it possible to write own functions with the tree dots and if yes
what's wrong with the following example?
test <- function(x, ...)
{
print (x)
if (exists("y"))print(y)
if (exists("z"))print(z)
}
test(4,y=2)

assigning NULL to a list element
Hi everyone,
For reasons beyond the scope of this message, I'd like to append a
NULL element to the end of a list.
tmp0 <- list(a=1, b=NULL, c=3)
append(tmp0, c(d=4)) ## works as expected
append(tmp0, c(d=NULL)) ## list with a/b/c only
Given that I could use
tmp0$a <- NULL
to remove 'a', I seem to understand why appending NULL returns me the
original list... But how should I

name of the variable that will contain the result of a function
Hi everyone,
say I have a function called 'foo', which takes the argument arg1.
Is there any mechanism that I can use to "learn" about the variable
where foo(arg1) is going to be stored?
For example:
x <- foo(arg1)
so, inside foo() I'd like to be able to get the string "x".
if,
foo(arg1)
was used insted, I'd like to get NA.
thank you very much,

customizing global request handler
what is the cleanest way to do something for every request of a particular type (Verb, and Content-Type header)? i''m trying to figure out if shipping a custom camping.rb is avoidable, and if, how i should structure a patch
my app http://whats-your.name/yard/ uses exclusively JSON based messaging between server and client. this means POST bodies are JSON, and not querystring.. camping
