[R] Store filename

[DAVID ARTETA GARCIA]

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
