Hi all,

I want to do the following:

data<-data.frame(col1=c(1,2,3,4,5))

getcol2<-function(data){
    data$col2[data$col1<=2]="L"
}

getcol2(data)

Unfortunately in the above col2 does not appear in the final data. So how
would you pass this by reference such that you would get it back?

Thanks,
Sachin
