Hi,
Thanks but I had already fixed that part.
My problem is I am not getting a value for the maxcls or mincls:
here is the code:
> dset1<-cbind(AGE,BMI,DEATH)
> BMIGRP<-cut(BMI,breaks=c(14,20,25,57),right=TRUE)
> AGEGRP<-floor(AGE/10)-2
> dset<-cbind(AGEGRP,BMIGRP,DEATH)
> maxage<-max(dset[,1])
> minage<-min(dset[,1])
> maxcls<-max(dset[,2])
> maxcls
[1] NA
After performing the cut function i get the different categories which are
labelled as (a,b] by default. I wanted to change them to categories 1 ,2 and 3
respectively so that I get a value for maxcls and mincls.
How do I change the 3 categories (14,20],(20,25],(25,57] to 1,2,3
respectively?
Thanks,
Anamika

which you have shown commented out select a full column.
You probably want the min and max of that column.
With your definitions, mincls:maxlcs has the same type of behavior as
(1:3):(1:3)
