Hi Petr,

I am an old FORTRAN programmer and new to R. The 'philosophy' of R is very very far from FORTRAN ! So, may be I am wrong but :

I want to test 3 projects. In fact, these 3 projects are identical but not in the same directory : one within Git (a source management), one on the server and the last one on my local machine. When I run the one in Git, R bombs (and I have no error code, line number, ...). I try to detect what is wrong. So I add cat(), browser() ... to try to 'narrow' the fault (is that clear ?) and the "source()" command is in my target. So I change the current project every 5 minutes ... So when I launch (start ?) the execution of one project and in some functions , I'd like to have the path + name of the .R file being used (perhaps the 'main' file of Git project is doing a source() on a file on the server instead of the one on the Git directory : do you see what I am looking for ?). In other words, I am not sure 100% of the "source()" command and I want to verify it ...

Jean
