[R] replacement has *** rows, data has ***

[Manqing Liu]

Hi all,

I created a predicted variable based on a model, but somehow not all
observations have a predicted value. When I tired to add the predicated
value to the main data set (data$pr <- pr) , it said:
replacement has 34333 rows, data has 34347.
Do you know how to solve that?

Thanks,
Manqing
