set.portfolio.moments_v1(R, constraints, momentargs = NULL, ...)
an xts, vector, matrix, data frame, timeSeries or zoo object of asset returns
an object of type "constraints" specifying the constraints for the optimization, see constraint
list containing arguments to be passed down to lower level functions, default NULL
any other passthru parameters FIXME NOTE: this isn't perfect as it overwrites the moments for all objectives, not just one with clean='boudt'
