random_portfolios_v1: generate an arbitary number of constrained random portfolios

In PortfolioAnalytics: Portfolio Analysis, Including Numerical Methods for Optimization of Portfolios

Description

repeatedly calls randomize_portfolio to generate an arbitrary number of constrained random portfolios.

Usage

random_portfolios_v1(rpconstraints, permutations = 100, ...)

Arguments

rpconstraints	an object of type "constraints" specifying the constraints for the optimization, see constraint
permutations	integer: number of unique constrained random portfolios to generate
...	any other passthru parameters

Value

matrix of random portfolio weights
