Hi,
I would consider the calculation of r-squared in the following to be a
bug, but then, I've been wrong before. It seems that R looks to see if the
model contains an intercept term, and if it does not, computes r-squared in
a way I don't understand. To my mind, the following are two alternati
Have you considered the example provided in the documentation "?glm" in
R 1.8.0? If that does not satisfy your needs, please explain why it
doesn't.
hope this helps. spencer graves

Hola!
In the lattice function splom, is it possible to get
the tickmarks/value labels _outside_ the scatterplot matrix,
and not inside each of the panels in the antidiagonal of panels
with variable labels?

Bernd,
for counts use histogram instead of barchart, and leave the left side of the
formula empty.
library(lattice)
meta<-read.table("meta.txt",header=T)
histogram(~daten.COUNTRY|daten.STATUS,data=meta)
Check "scales" in xyplot (it's also valid for histogram) so you get the
names of the

There may be an easier way, but reinstalla
