Please read the Posting Guide and after doing so repost with a question that admits of some possiblity of answering.

Yes, and that, too.

Run with:

options(error=utils::recover)

Then at the point of the error you will be able to examine sigma2$id
which is probably not a numeric.  Any time you get an error like this,
if you have been using the above statement in your script (which I
always have turned on), you will be able to discover for yourself most
of your bugs.  Debugging is an important talent to learn if you are
going to be writing programs/scripts.

In case you need the URL: http://www.r-project.org/posting-guide.html

  Some google-detection (searching for "if sigma2$id error")
suggests that the OP is using the ercomp package, but beyond
that the question is still (as you suggest) unanswerable.

Does that have advantages of using a browser() line or two?  I find
them indispensable.

The error=utils::recover option will invoke a browser at the time of an 
error, so it's very helpful when you don't know where to put the 
browser() calls.

You should also consider using trace(), which inserts temporary 
browser() calls (or other code).  The setBreakpoint() function 
constructs a call to trace() using source file information and is often 
an easier front end.
