Well, obviously the interface to .Internal(identical) changed between

Anyways, find where you use it in your script and then we can help --
there's not much we can do without seeing the relevant line of code.

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.

Hello, I've just installed R-2.15.0 (I've had R 2.13.2 before it and I've
deleted everything before I started to install new version).

When I've tried to run my script by command "source()" I received this
message:
Error in source("script.R") :
  7 arguments passed to .Internal(identical) which requires 6

I know I should delete my $R_HOME but it contain only one string:
[1] "C:/PROGRA~1/R/R-215~1.0"

I don't know what's happened.

Thank you!
