R help - Jul 2005 - bug in chdir option of source

I'm on R 2.1.0.

In the "source" function there is a bug preventing the proper use of
the
chdir option (which simply doesn't work).

The problem is that in the function the following line occurs:
 file <- file(file, "r", encoding = encoding)

This overwrites the variable "file" and later causes the check
    if (chdir && is.character(file) && (path <-
dirname(file)) !        ".")
to fail.

I have some generic files which are not yet a package that I regularly
want to source into many other files. How do people handle situations like
this right now?

Thanks, Stefan

They use R-2.1.1 where the bug has been fixed.

Please read the posting guide (as we do ask) and use the current version 
as it asks to see if the `bug' has already been fixed.

This was fixed a while ago, definitely in 2.1.1.

I apologize for not having investigated enough.

However I want to bring up the point that upgrading can be a very
tedious thing. I administer a cluster for which upgrading brings it to a
halt for several hours stopping all calculations going on. At the moment
I have no way to go from 2.1.0 to 2.1.1.

I just want to add this point to the release policy of R which
historically has very quick release cycles which on the one hand is a
very positive thing but on the other hand can be problematic with
respect to some aspects.

Thanks again, Stefan
