For the binomial the standard link function is the logit:

In the binomial glm model the observed y values are 0, or 1 which give g(0) =

May be this helps:
jaw-data.frame(vara=1:20,age=runif(20))
for (i in 2:6) {
jaw[paste(agepow,i, sep=)] - jaw[age]^i
}
jaw-round(jaw,2) # It is just to help the check task

Thank you for your answer!

Thank you to all for your ideas. They all solved my problem nicely.
And I learned about paste() too!

The sqldf R package can do that using SQL syntax. See:
http://sqldf.googlecode.com
The R merge command can do a join but not using SQL syntax.
See ?merge

Hi All,
I'm wondering whether there is a quick way to know the position of a specific
charcater in a long character:
for example
frg=((D:41.04,I:41.04):45.05,(((E:2.32,((G:0.67,J:0.67):0.44,H:1.11):1.21)
and I would like to know that the 1st, 2nd, 26th, 27th, 28th ... character is

Well, actually, what I really want is a way to quickly find the fragment that
contained equal number of ( and ), starting from the end of the character.
In the case of
frg = =((D:41.04,I:41.04):45.05,(((E:2.32,((G:0.67,J:0.67):0.44,H:1.11):1.21)
that means finding the part:

R-devotees,
I have a question about modeling in the case where the response variable is
binary.
I have a case where I have a response variable that is the probability of
success, and four descriptor variables, The response has a sigmoid response
with one of the variables. I would like to test
I have a table of data, and columns 6-8 of row 1 each contain an array. How
do I extract those arrays and plot them against eachother? Here is my
current code, which only plots the first point of the array.

triax.points(

I'm having a problem with rgl.snapshot. If I run the following code *once* and
*once only*, all is well.

And the pic.png looks right. But if I try to rerun rgl.snapshot
Hello,
I am trying to select the following headers from a data frame but when I try
and run the command it executes halfway through and give me an error at V188
and V359.

Hi Kevin, you mean an s-shaped relationship of a variable with your response?
So you have a response that is strictly constrained to the interval 0,1 or,
and these limits are not due to truncation or censoring (i.e. your response
variable is truly a proportion).
This sounds like a good
Wait, are the proportions (probabilities) based on discrete data, or are
they truly continuous? If the latter, then beta regression might be more
appropriate (e.g. package betareg). If the former, include the sample
size for each proportion in the call to glm using the weights= argument.
Or set
Dear R Help,
At the risk of sounding naïve, is there a way for obtaining something
resembling an r^2 value for the fit obtained using SSasymp?
I have read ?SSasymp and looked through the archives but to no avail.
Many thanks,

I have a connector-question to that. Is beta-regression available for
repeated measures or panel data and if so is it available in R?
thx,
Daniel

Jim Lindsey's repeated package has the function gnlmm which will fit
beta regressions with a random intercept and one level of nesting. I
don't know of any other options.

I have:
sc - split(x, list(x$Category, x$SubCategory), drop=TRUE)
I think I understand 'length(sc)' It would be the total number of non empty

I don't seems to be able to iterate
