How to apply SSfpl with binary data
Dear R-help subscribers
Would you tell me how to apply SSfpl with binary data as below?
Unfortunately, there is not the EXAMPLE in help(SSfpl) for binary data but for quantitative data(Chick).
V1: dose
V2: log-transformed dose
V3: response (rate)
V1 V2 V3

lmList and lapply(... lm) different std. errors
Am I trying to perform multiple linear regressions on each 'VARIABLE2'. I
figured out that there are different ways, using the following code: (data
is given at the end of this message)
reg <- lapply(split(TRY, VARIABLE2), function(X){lm(X2 ~ X3, data=X)})
lapply(reg, summary)
Which produces the following:
$`1`
Call:
lm(formula = X2 ~ X3, data = X)
Residuals:
Min

Looping through R objects with $ operator and tags
Hi all,
Suppose I want to set the values in a column to the log of the values
of another column like so:
object$LogDist <- log10(object$Distance)
How do I loop through the objects if I have object1, object2, etc to
perform this function?
object1$LogDist <- log10(object1$Distance)
object2$LogDist <- log10(object2$Distance)
object3$LogDist <- log10(object3$Distance)
I was trying to

Unrealistic dispersion parameter for quasibinomial
I am running a binomial glm with response variable the no of mites of two
species y->cbind(mitea,miteb) against two continuous variables (temperature
and predatory mites) - see below. My model shows overdispersion as the
residual deviance is 48.81 on 5 degrees of freedom. If I use quasibinomial
to account for overdispersion the dispersion parameter estimate is 2501139,
which seems

experiments with slot functions and possible problems NOTE
Hello,
first of all, thanks to LT for \pkg{codeutils}. I agree that it is
indeed very useful to identify errors and also to encourage re-thinking
past solutions. My problem:
I want to compare different sets of related sub-functions which should
be used alternatively by the same top-level function. Sets of related
functions should be bound together (as lists) and the workspace should
be as clean
