René,
Yes, to fit a re-parameterized logistic model I think you'd have to code the
whole enchilada yourself, not relying on glm (but not nls() as nls() deals with
least squares minimization whereas here we want to minimize a minus log
binomial likelihood).
I did that and have the

Depends on how you want to 'check'. I usually use 'View' to see if the data

Dear Experts,
When using plot and polygon, I can change the density and angle of the
shaded area lines when plotting is done in regular scale. It does not seem
to work in 'log' scale. Any suggestions would be highly appreciated!
below is an example:
Hi all,

I am having the following weird problem when debugging R programs

Hello,
I want to create side-by-side maps of similar attribute data in two
different cities using a single legend.
To simply display side-by-side census block group boundary
(non-thematic) maps for Minneapolis Cleveland I do the following:
library(rgdal)
library(sp)
Use `lm` the way it is designed to be used, with a data argument:
l2 - lm(e~. , data=as.data.frame(M))
summary(l2)
Call:
lm(formula = e ~ ., data = as.data.frame(M))
And what is the regression being done in this case? How are the
independent variables used?
It looks like
In your code by supplying a vector M[,e] you are regressing e
against all the variables provided in the data argument, including e
itself -- this gives the very strange regression coefficients you
observe. R has no way to know that that's somehow related to the e
it sees in the data argument.

Duh! Silly me! But my confusion persits: What is the regression being
done? See below

Sigh Please note that your df and M are undoubtedly different
objects by now:
M - matrix(runif(5*20), nrow=20)
colnames(M) - c('a', 'b', 'c',
