Dear Researchers,

I have a data.frame with 2 columns like this:

mydf <-
data.frame(value=c(1,2,3,4,5),ID=c("Area_1","Area_2","Area_3","Area_4","Area_5"))

> mydf
  value     ID
1     1 Area_1
2     2 Area_2
3     3 Area_3
4     4 Area_4
5     5 Area_5


I need to convert the *ID *in the following version
> mydf
  value     ID      newID
1     1 Area_1   AreaSample1
2     2 Area_2   AreaSample2
3     3 Area_3   AreaSample3
4     4 Area_4   AreaSample4
5     5 Area_5   AreaSample5

some people know the right function to split ID and create a new column

Thanks in advance
Gianni
