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?

First, you should read the Posting Guide. Then you should read the help page for ?predict. Only then should you write a follow-up email (in plain text) with code that constructs a simple example using whatever method was used to construct this `pr` variable and provide enough information to support a sensible answer.
