I don't succeed to access to a directory with open source R's spotfire console

Hi everyone,

 

I'm trying through a r code in spotfire to access to a directory.  When I'm using the spotfire console : tibco enterprise runtime for R my code : my line  fichiers <-dir(path = "//***/*****/****/****") is running well but when I try to execute this same coding with console 'R script  open source R' it fails...  My variable fichiers is empty (with no file names into).

 

Can someone help me please?

Thanks in advance
