Hi Gabriel,
I actually want to make renames over thousands of files. But if I am not able to express the source filename of the rename operation I will not be able to get the work done. Besides the fact that there are issues I think that R is qualified for solving my problem by the method how it can handle long vectors of strings, booleans and also lists.
Kind regards,
Frank
