Hi R helpers!

I'm still a bit ( alot) confused by the use of "inverseTrans" and "ytype" in areg.boot (Hmisc): What I want to do seems very simple, but I do not get the result I want:
plot the predicted values in the original scale. (I did not understand the documentation, sorry!)


for instance the following code
f<-areg.boot(Pe[here]~monotone(t[here])+monotone(v[here])+I(Pa[here]-Pm[here])+......,B=100)

f.origScale<-Function(f,ytype="inverse")                         #  works up to here OK, back to original Pe scale



 Now if use predict() to make prediction for given input values , how do I transform the result back into the original response scale?

(in the documentation:

 A 'predict' method computes predicted
     values on the original or transformed response scale, or a matrix
     of transformed predictors)



so I tried 

y.predicted<-predict(f,data2predict, type='inverse')   #result is in transformed scale

y.predicted<-predict(f,data2predict, type='fitted',scale="original")....without success

(I did not find the documentation for the predict method of areg.boot)





as the inverse transformation of response obtained by areg.boot is not analytical, I do not see how I can use inverseTrans 



.



Thank for any help



Anne
