It may not be in his code.  What is odd is that R 2.15.0's identical() 
does require 6 arguments, whereas in R >= R-patched it accepts 6 or 7.

So it looks like something has been done under a later version of R, and 
the usual culprit here is an S4-using package which has captured the 
definition of identical() from a later version of R.

Updating to R-patched may solve the problem.
