str and class
...ution is to use more sensibly named attributes, but str
could be made more foolproof by using
attr(object, "class", exact = TRUE)
instead.

Model formula question
Hi all,
I'm not familiar with R programming and I'm trying to reproduce a
result from a paper.
Basically, I have a dataset which I would like to model in terms of
successive increments, i.e. (y denote empirical values of y)
y_1 = y1,
y_2 = y1 + delta1,
y_3 = y1 + delta1 + delta2.
...
y_m = y1 + sum_2^m delta j
where delta_j donote successive increments in the y-values, i.e.
delta

Incorrect fix for PR#9316: Cook's Distance & plot.lm
...unts
for the inconsistency reported in PR#9316.
The solution is simply to plot the standardised Pearson residuals
instead, as in the attached patch.
Best regards,
Heather

Understanding glm family documentation: dev.resids
Hi all
Consider the family function, as used by glm. The help page says the value of the family object is a list, one element of which is the following:
dev.resids function giving the deviance residuals as a function of (y, mu, wt).
But reading any of the family functions (eg poisson) shows that dev.resids is a function that computes the *square* of the deviance residuals (at least, by

nls: Fitting two models at once?
Hello,
I'm still a newbie user and struggling to automate some analyses from
SigmaPlot using R. R is a great help for me so far!
But the following problem makes me go nuts.
I have two spectra, both have to be fitted to reference data. Problem: the
both spectra are connected in some way: the stoichiometry of coefficients
"cytf.v"/"cytb.v" is 1/2.
