Hi,
I just noticed that (with my version 4.2.0) it is no longer possible to
use glm with family=binomial(link=identity). Why is that? It was
possible with 4.0.x as a colleague of mine just confirmed. After all it
is useful to compute risk differences with factors.

Hi,
after having read here about the "seed problem" I wonder if there is a
way to automatically exclude certain variables from being saved when the
workspace image is saved at the end of an interactive session. I have
been using .First() and .Last() for ages but apparently they are of no
help as .

Hi,
In short: Is it possible to have the previously saved workspace restored
and nevertheless load a function already existing in this workspace via
.Rprofile anyway?
In detail: I use different directories for different projects. In all
those projects I use a function which I therefore try to get

Hi,
I have to compute the singular value decomposition of rather large
matrices. My test matrix is 10558 by 4255 and it takes about three
minutes in R to decompose on a 64bit quadruple core linux machine. (R is
running svd in parallel, all four cores are at their maximum load while
doing this.) I
How can I automatically exclude one variable from being saved in the
workspace when I quit an R session? The problem is I don't know how to
erase a variable once it has been created.
Background: I open a connection called "con" to a database server in my
~/.Rprofile. Obviously, the connection expi

Hi,
after updating to 2.7.0, command line completion doesn't work anymore. I
understand that the package rcompgen is now part of utils. I hadn't used
rcompgen before but completion worked without it (I double checked it
using an 2.6.2 version on another machine). Now, it doesn't work, even
after s
Hi,
is there an R-implementation of the RANSAC-algorithm?

Hi,

How can I use "Anova" from the car package to test a modell without
