Dear List,
I'm having problem with an exercise from The R book (M.J. Crawley) on page
567.
Here is the entire code upto the point where I get an error.
data(UCBAdmissions)
x - aperm(UCBAdmissions, c(2, 1, 3))
names(dimnames(x)) - c(Sex, Admit?, Department)
ftable(x)
fourfoldplot(x, margin = 2)

Hi Romain,
It works for me:
model1 - glm(as.vector(x) ~dept*sex*admit,poisson)
model1
Call: glm(formula = as.vector(x) ~ dept * sex * admit, family = poisson)
Coefficients:
(Intercept) dept2 dept3 dept4
dept5
6.23832
Thank you Jorge and Barry for your input.
I've fiddled around a bit and as a result, am even more confused. If I start
R console via Notepad++ (I use Npp2R) and execute the model1, it goes
through just fine. Here is the sessionInfo() for this working session:
sessionInfo()
R version 2.9.2
Check to see if you have an old workspace being loaded. You might have an
object called 'family' which you might need to remove.

Hello Sundar,
I checked the ls() and it was full of something (something that I should
have removed long ago but was not diligent enough). I have cleared the list
(via rm(list=ls()) and the glm function works fine now.
Cheers,
Roman
