R help - Oct 2005 - how to predict with logistic model in package logistf ?

dear community,
     I am a beginer in R , and can't predict with logistic model  in package
logistf,
could anyone help me ? thanks !

the following is my command and result :
>library(logistf)
>data(sex2)
>fit<-logistf(case ~ age+oc+vic+vicl+vis+dia, data=sex2)
>predict(fit,newdata=sex2)
   Error in predict(fit, newdata = sex2) : no applicable method for 
"predict"

Did you try fit$predict?

Not exactly the answer to your question, but an alternative to the 
logistf package, which purports to do similar things, is brlr (which 
does provide a predict method).  Does this work for you?

   library(brlr)
   data(sex2)
   fit <- brlr(case ~ age + oc + vic + vicl + vis + dia, data = sex2)
   predict(fit, newdata = sex2)
