This is already fixed:

     o	source(file, chdir = TRUE) was not checking that 'file' was a
 	filepath (rather than a URL).  For 2.1.0 only, it did not work
 	even if 'file' was a filepath.

>From the R FAQ:

    Before you actually submit a bug report, you should check whether the 
bug has already been reported and/or fixed.  First, try the "Search 
Existing Reports" facility in the Bug Tracking page at 
`http://bugs.R-project.org/'.  Second, consult 
`https://svn.R-project.org/R/trunk/NEWS', which records changes that will 
appear in the _next_ release of R, including some bug fixes that do not 
appear in Bug Tracking.  (Windows users should additionally consult 
`https://svn.R-project.org/R/trunk/src/gnuwin32/CHANGES'.)  Third, if 
possible try the current r-patched or r-devel version of R.  If a bug has 
already been reported or fixed,
please do not submit further bug reports on it.
