Return.cumulative = as.xts( Return.cumulative)Ĭolnames( Return.cumulative) = columnnamesĬhart.TimeSeries( Return.cumulative, colorset = colorset, plot.engine = plot.engine, legend.loc = legend.loc. Generate a cumulative return plot with the chart.CumReturns function. A vertical color ramp in R is not possible using base graphics, and conveys no information anyway. colors for them, and optionally add labels to some or all of your ranges. The colorsets provide different colors for the different chart elements, and work best when you plot more than one series on the same chart, to compare an asset to an index or a peer group, for example. Next I construct lists of 6 months worth of daily returns using the rollingorigin() function from the rsample() package. I then convert the daily asset prices to daily log returns using the periodReturn function from the quantmod() package. Return.calculate is located in package PerformanceAnalytics. Return.cumulative = merge( Return.cumulative, ) Numbers Trend Progress bar Gauge Table Pivot table Line chart Bar chart. This chapter is for improvement of the last issue of Markowitz’s portfolio: it only considers the risk of the portfolio as a whole and ignores the risk diversification (i.e. The data: The data is collected using the tidyquant() package’s tqget() function. calculate simple or compound returns from prices. #' wealth.index if \code, one = one, geometric = geometric) #' R an xts, vector, matrix, data frame, timeSeries or zoo object of #' Cumulates the return series and displays either as a wealth index or as The other data provide some context, so they are graphed in diminishing values of gray. These palettes are best used when there is an important data set for the viewer to focus on. #' Chart that cumulates the periodic returns given and draws a line graph of The first category of colorsets are designed to provide focus to the data graphed as the first element, and include redfocus, bluefocus, and greenfocus. #' Cumulates and graphs a set of periodic returns Cumulates and graphs a set of periodic returns Description Chart that cumulates the periodic returns given and draws a line graph of the results as a 'wealth index'.
