HELP!!!

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.

I am sorry to bug you, I am having this error whenever I want to run
random effects regression in software R: Error in if (sigma2$id < 0)
stop(paste("the estimated variance of the",  :
   missing value where TRUE/FALSE needed.

Please help me look into it.
