chart.Concentration: Classic risk reward scatter and concentration

Description

This function charts the optimize.portfolio object in risk-return space and the degree of concentration based on the weights or percentage component contribution to risk.

Usage

chart.Concentration(object, ..., return.col = "mean", risk.col = "ES", chart.assets = FALSE, conc.type = c("weights", "pct_contrib"), col = heat.colors(20), element.color = "darkgray", cex.axis = 0.8, xlim = NULL, ylim = NULL)

Arguments

object
optimal portfolio created by optimize.portfolio.
...
any other passthru parameters.
return.col
string matching the objective of a 'return' objective, on vertical axis.
risk.col
string matching the objective of a 'risk' objective, on horizontal axis.
chart.assets
TRUE/FALSE. Includes a risk reward scatter of the assets in the chart.
conc.type
concentration type can be based on the concentration of weights or concentration of percentage component contribution to risk (only works with risk budget objective for the optimization).
col
color palette or vector of colors to use.
element.color
color for the border and axes.
cex.axis
The magnification to be used for axis annotation relative to the current setting of cex.
xlim
set the x-axis limit, same as in plot.
ylim
set the y-axis limit, same as in plot.
