I got it right now, It wasn't working because the matrix of predictors had
the same name as the dataset, so I modified the call
creating a dataset with the response and predictors and keeping the
data.frame using the same name
metodocentrod <- data.frame(metodocentro)
resultadocentro <- glm(Ycentro ~ metodocentro-1, family = binomial(link =
"logit"), data=metodocentrod)
Thanks for the help, because of your e-mail I could figure this out.
