exactly what I am looking for, but I apologize if the question was already
asked.
I have 10 different treatments and want to know whether they affect the sex
ratios of insect emergence. After running the glms I
Thanks Gaurav,
I'll try this and get back to you.

okay, I played a bit around and now I have some kind of testcase for you:
v1 - NA
v2 - rnorm(6)
v3 - rnorm(6)
v4 - rnorm(6)
v5 - rnorm(6)
v6 - rnorm(6)
v7 - rnorm(6)
v8 - rnorm(6)
v8 - NA
list - list(v1,v2,v3,v4,v5,v6,v7,v8)
categ - c(NA,cat1,cat1,cat1,cat2,cat2,cat2,NA)

LS,
I'm estimating multilevel regression models, using the lme-function
from the nlme-package. Let's say that I estimated a model and stored
it inside the object named 'model'. The summary of that model is
shown below:
Using summary(model)$tTable , I receive the following output:

I assume if you want the components to be NA then you really intend
the result to be a numeric vector. The following replaces all non-digits
with (thereby removing them) and then uses as.numeric to convert the
result to numeric. Just omit the conversion if you want a character
vector result:
gsub( , , gsub(%, , gsub([a-z], , c(tr3,jh40%qs dqd

Dear useR,
I have a data matrix, it has n columns, each column is a two-level
variable
with entires -1 and +1. They are randomly generated, now I want to order
them like (for example, 5 columns case)
--- - -
-- - -
This is giving you exactly what you are asking for. The operator * does
element by element multiplication. So, .48 + -.48 =0, right? Is there
another mathematical possibility you were expecting?
