I am using SIAR - SIBER and have for a few months now. I went back to check some figures with code that I had previously used without a problem. I have since ran the sample data within the package and somebody else’s data and code yet  theirs works and I get the same error Error: not a matrix when bayesian stats are about to be used. I have recently update my osx system to El captain - but everything that I have recently tried works. Does anyone have any suggestions. I have updated, and reinstalled R.

After you get the error, call traceback().  That will usually tell you
where the error occurred by listing the call stack at the time of the
error.
