Help with Logit Model
Hello,
I have a bit of a tricky puzzle with trying to implement a logit model
as described in a paper.
The particular paper is on horseracing and they explain a model that is
a logit trained "per race", yet somehow the coefficients are combined
across all the training races to come up with a final set of coefficients.
My understanding is that they maximize log likelihood across the

...rix.type = "edgelist")
# Plot the network:
gplot(dat.edg, displaylabels = TRUE, label.cex = 0.9, arrowhead.cex =
0.9,
vertex.col = "red")
Is there any way you know of scaleing the size of the nodes in the
graph? I was hoping to scale the nodes according to their individual
betweeness score. Betweenness can be calculated for each node in the
example above, using:
betweenness (dat.edg)

Hope you can help ... many thanks,

removing daylight savings in R
Hi all,
I've been having some trouble with times in regards to daylight savings in R
version 2.8.1. I have an ORACLE database that R is importing data in from,
for the 2am and 2:30am time intervals for the dates that daylight savings
starts the times are getting read as NA values into R. I'm also finding that
if I open a R workspace from version 6.2.2,the datetimes are

Clunky Xorg with latest 6.7 upgrade?
Is it just me or does Xorg/Gnome seem slow and clunky to any other
desktop users once the 6.7 upgrade is done?

Clunky Xorg with latest 6.7 upgrade?
...FF accumulates resources and has
an ever-increasing CPU usage with what I normally have running.
But even in those cases I didn't see a "jerky" and lagging selection
window when I was selecting a region with ksnapshot. The usual symptom
was a slow redraw of FF windows when I switched between them or betwee
virtual desktops. I am *not* seeing those symptoms with the current
issue - looks like FF and plugins container (I wonder if I can eliminate
that - not sure it's needed?) is behaving OK.
Ended the trade screens applet and tried selection of a region with
ksnapshot - same result...

Woodpeckers Revisited
Just when I thought I couldn't be wrong, I was wrong. We have
woodpeckers that drill into the arial telephone cables, and water seeps
through the holes and partially grounds the tip and/or ring wires
causing hum. I thought the hum/buz on my lines was a telco problem.
The Qwest HQ noise team assures me that my lines are within spec. Sure
enough, when I listen on the test set the lines

optimization problem in R ... can this be done?
Im trying to ascertain whether or not the facilities of R are sufficient for solving an optimization problem I've come accross. Because of my limited experience with R, I would greatly appreciate some feedback from more frequent users.
The problem can be delineated as such:
A utility function, we shall call g is a function of x, n ... g(x,n). g has the properties: n > 0, x lies on the
