Hi Henrique, Daniel and Jim, and rest of the list. Your comments have been really useful. Daniel, you mention whether I am looping over some files stored in a directory. Is that actually doable with R? I mean, is it possible to read all the files in the same directory and run my script through them?

Regards,

David
