This function provides a logical test of whether or not a given list
  of data meets minimum criteria to be considered data for
  IterativeQuadrature, LaplaceApproximation,
  LaplacesDemon, PMC, or
  VariationalBayes.
is.data(Data)This is a list of data. For more information, see the
    LaplacesDemon function.
The is.data function returns a logical value. It returns
  TRUE if Data meets minimum requirements to be considered
  data in this package, and FALSE otherwise.
This function is useful for testing whether or not a list of data
  meets minimum criteria to be considered data in this package. The
  minimum requirements are that Data is a list, and it contains
  mon.names and parm.names.
This function is not extensive. For example, it does not match the
  length of parm.names with the length of Initial.Values,
  or compare the length of mon.names to the number of monitored
  variables output from the Model specification
  function. Additional checks are conducted in
  IterativeQuadrature, LaplaceApproximation,
  LaplacesDemon, PMC, and
  VariationalBayes.
