Violation of sample independence in Pearson's product-moment correlation
...assumption of sample independence for Pearson's
test, and I should have had only 7 points, which would reflect the means of
my two variables for each individual animal across 10 days. Is this
appropriate or is there a means of accounting for repeated sampling with a
correlation test?

coxph() command design and data setup
...block?
Additionally, I have a frequency column in data.table that indicates how
many of a particular observation occurred in each row. Is it appropriate to
assign this column as a weigh argument in cosph? If so, how is that done?
I can send sample data if necessary. Thanks for any help!

coxme() random effect syntax
...+ SUBSZ + CFSZCL:SUBSZ, data =
data.table)
However, I would like to add rock movement (BEDLOAD) as a random
co-variate, which is not possible with the coxph() function. Is it
possible to do so with coxme() in the kinship package? If so, what is
the proper syntax?
Thanks for any help.

Testing treatment effects on exponential decay models
...above model for each treatment and approximate k, but I would like
to examine treatment effects on these fits as I might using glm(). If I can
get passed this hurdle, I may also inquire about adding a random effect as
well.
If it helps, I can post a subset of data. Thanks for any help.

coxph models for insects
...f 4
observations or insects, all within 1 treatment. The block variable is room,
where each room contains ~40 chambers each of which has been randomly
assigned a treatment. I believe that I have chamber %in% treatment right in
representing my data, but how do I account for room as a block?

Find the first values in vector
Hi !
I have a vector:
vec= TRUE TRUE TRUE TRUE FALSE FALSE FALSE FALSE TRUE TRUE FALSE
and I'm looking for a method which let me get only the first values equal
TRUE from this vector. It means that I want to get a vector:
vec_out = TRUE TRUE TRUE TRUE
or posictions values = TRUE: vec_out = 1,2,3,4
