## the method is very simple as the program hclust works.

passing formula arguments cv.glm
...ta[2]
print("cv.glm OK")
}
When I run the above function line by line with the arguments from
below, it works fine. But when I call it as function, I get this :
rm( glmfit, formu, cv.err ) # cleanup if required
logistic.LOOCV.err( formu=as.formula(r~stage+xray+acid), data=nodal )
logistic.LOOCV.err( formu=as.formula(r~stage+xray+acid), data=nodal )
[1] "glmfit is OK"
Error in model.frame(formula = formu, data = data[j.in, , drop =
FALSE], :
Object "formu" not found
I think this has something to do with formula and environments but I do
not know...

question
Sir,
I found your description of the dataset about nodal involvement in prostate cancer. It comes from the book biostatistics casebook. I like to use the dataset for doing logistics regression. Can you tell me where I can find the dataset.
Thanks and greetings
