meanvar.efficient.frontier

Generate the efficient frontier for a mean-variance portfolio

Description

This function generates the mean-variance efficient frontier of a portfolio specifying the constraints and objectives. The portfolio object should have two objectives: 1) mean and 2) var (or sd or StdDev). If the portfolio object does not contain these objectives, they will be added using default parameters.

Usage

meanvar.efficient.frontier(portfolio, R, n.portfolios = 25,
  risk_aversion = NULL, ...)

Arguments

`portfolio`	a portfolio object with constraints created via `portfolio.spec`
`R`	an xts or matrix of asset returns
`n.portfolios`	number of portfolios to plot along the efficient frontier
`risk_aversion`	vector of risk_aversion values to construct the efficient frontier. `n.portfolios` is ignored if `risk_aversion` is specified and the number of points along the efficient frontier is equal to the length of `risk_aversion`.
`...`	passthru parameters to `optimize.portfolio`

Value

a matrix of objective measure values and weights along the efficient frontier
