This function produces a stacked barplot of weights along an efficient frontier.
chart.EF.Weights(object, ...)# S3 method for efficient.frontier
chart.EF.Weights(object, ..., colorset = NULL,
n.portfolios = 25, by.groups = FALSE, match.col = "ES", main = "",
cex.lab = 0.8, cex.axis = 0.8, cex.legend = 0.8, legend.labels = NULL,
element.color = "darkgray", legend.loc = "topright")
# S3 method for optimize.portfolio
chart.EF.Weights(object, ..., colorset = NULL,
n.portfolios = 25, by.groups = FALSE, match.col = "ES", main = "",
cex.lab = 0.8, cex.axis = 0.8, cex.legend = 0.8, legend.labels = NULL,
element.color = "darkgray", legend.loc = "topright")
object of class efficient.frontier or optimize.portfolio.
passthru parameters to barplot.
color palette or vector of colors to use.
number of portfolios to extract along the efficient frontier.
TRUE/FALSE. If TRUE, the group weights are charted.
string name of column to use for risk (horizontal axis). Must match the name of an objective.
title used in the plot.
the magnification to be used for x-axis and y-axis labels relative to the current setting of 'cex'.
the magnification to be used for sizing the axis text relative to the current setting of 'cex', similar to plot.
the magnification to be used for sizing the legend relative to the current setting of 'cex', similar to plot.
character vector to use for the legend labels.
provides the color for drawing less-important chart elements, such as the box lines, axis lines, etc.
NULL, "topright", "right", or "bottomright". If legend.loc is NULL, the legend will not be plotted.
