   As the error message says, there is a problem computing
the initial values for the model fitting procedure. These
initial values may be hidden within the code you are using.

  Please read the posting guide -- we need a lot more information
before we can help you.  If at all possible provide a reproducible
example, and tell us what packages/functions you are using (and
the output of sessionInfo() ).

  good luck
