#R to do

Change the names of files in a directory. This is useful for changing the names of a set of files from a tag deployment to a different format. Only the first part of the name matching the prefix is changed - any trailing letters or numbers are kept. Careful: things can go very wrong when messing with valuable data files. Always do a check first on some dummy files. There may also be better ways to do re-naming operations through your operating system.

prefix is a string containing the part of the file name to be changed.N/A
newprefix is a string containing the replacement.N/A
Output var Description Units
n is the number of files that were re-named. N/A
