no, if I close R then I can remove the file

nothing special a part from R studio

I have an url to access the pages of .tiff documents. The issue that I 
don't know how many pages have each documents. So I try to copy and 
incrememt the index for the number of pges until it failed. I know it is 
not an idea solution but this is I have now until we get this info into 
a DB.
> Would debugging in R Studio shed additional light?
I will give a try.

Thanks
Cheers
Fabien
