Hi Tammy, I think we need more information.
Are the names always four parts? Does the fix always involve moving two parts from the back to the front? For that matter, which of the two you gave is correct? Or does it matter what order the parts are in as long as it's consistent? Sorting them would be easiest, and would work regardless of number of parts and how they were entered. That could be done, for instance, with strsplit(), sort() and paste().
