extractEfficientFrontier {PortfolioAnalytics} | R Documentation |
Extract the efficient frontier data points
Description
This function extracts the efficient frontier from an object created by
optimize.portfolio
.
Usage
extractEfficientFrontier(
object,
match.col = "ES",
n.portfolios = 25,
risk_aversion = NULL
)
Arguments
object |
an optimal portfolio object created by |
match.col |
string name of column to use for risk (horizontal axis).
|
n.portfolios |
number of portfolios to use to plot the efficient frontier |
risk_aversion |
vector of risk_aversion values to construct the efficient frontier.
|
Details
If the object is an optimize.portfolio.ROI
object and match.col
is "ES", "ETL", or "CVaR", then the mean-ETL efficient frontier will be
created via meanetl.efficient.frontier
.
If the object is an optimize.portfolio.ROI
object and match.col
is "StdDev", then the mean-StdDev efficient frontier will be created via
meanvar.efficient.frontier
. Note that if 'var' is specified as the
name of an objective, the value returned will be 'StdDev'.
For objects created by optimize.portfolo
with the DEoptim, random, or
pso solvers, the efficient frontier will be extracted from the object via
extract.efficient.frontier
. This means that optimize.portfolio
must
be run with trace=TRUE
.
Value
an efficient.frontier
object with weights and other metrics along the efficient frontier
