Hi Nick, thanks for your reply. The problem is a bit more complicated. The issue is not that I have 11 files, but that I have some 400 variables in each file, each variable having a year tag at a random place in its name. Examples of variable names: permit09 , hab_ch09 , plingu09 , pdate09 , p09d160 , p09d161 , p09d162 . The "09" is the year tag, and I want to replace that with XX or somthing similar using a loop. I checked out the renvars package, but I don't see how I can avoid typing 400 variable names with it.
