Interactive Analysis of Systematic Investor - `PerformanceAnalytics` Tables

In a previous post, I thought it would be good fun to take one of the posts from Systematic Investor and d3-ify it. Let's have a look at returns now using the mutliple tables provided by PerformanceAnalytics. I will just use the defaults on each of these tables and then plot the table with a dimplejs bar chart.

Copy/Paste Systematic Investor Brilliance

As before, let's start by getting the data and performing the calculations in R. This is a direct copy and paste from the Systematic Investor post. Thanks again Systematic Investor.

`PerformanceAnalytics`, Please Make All Your Tables

#use rCharts to get some interactive plots
require(rCharts)
require(reshape2)
#Performance Analytics wants the return series so let's merge returns into
#a single xts object
returns.xts <- do.call(merge,
  lapply(
   names(models),
   FUN=function(x){
     x.data <- models[[x]]$equity[endpoints(models[[x]]$equity,"months"),]
     colnames(x.data) <- x
     x.ret <- ROC( x.data, type = "discrete", n = 1 )
     return(x.ret)
   }
  )
)[-(1:11),]  #remove first 11 months since no data; will need to change if not monthly
perfTables <- list()
perfTables$AnnualizedReturns <- table.AnnualizedReturns(returns.xts)
perfTables$Autocorrelation <- table.Autocorrelation(returns.xts)
perfTables$CAPM <- table.CAPM(returns.xts[,-1],returns.xts[,1])
perfTables$CalendarReturns <- table.CalendarReturns(returns.xts)[,-(1:12)]/100 #ignore monthly data
perfTables$CaptureRatios <- t(table.CaptureRatios(returns.xts,returns.xts[,1]))
perfTables$Correlation <- t(table.Correlation(returns.xts,returns.xts[,1]))
perfTables$Distributions <- table.Distributions(returns.xts)
perfTables$DownsideRisk <- table.DownsideRisk(returns.xts)[-7,] #remove drawdown

perfTables$SpecificRisk <- table.SpecificRisk(returns.xts[,-1],returns.xts[,1])
perfTables$TrailingPeriods <- table.TrailingPeriods(returns.xts)
perfTables$Variability <- table.Variability( returns.xts )

`rCharts`, Please Make Us Lots of Bar Charts

require(RColorBrewer)
lapply(
  perfTables, #["InformationRatio"],
  FUN = function(x) {
    x.df <- data.frame( rownames(x),x )
    x.melt <- melt( x.df, id.vars = 1 )
    colnames( x.melt ) <- c( "metric", "strategy", "value")
    d1 <- dPlot(
      x = "value",
      y = c("metric","strategy"),
      groups = c("strategy"),
      data = x.melt,
      type = "bar",
      width = 800
    )
    d1$chart( x = 150, width = 550 )  #move over a little to allow room for y axis labels
    d1$yAxis( type = "addCategoryAxis", orderRule = rev(x.melt$metric) )
    d1$xAxis( type = "addMeasureAxis", outputFormat = ".2%"  )
    d1$legend(
      x = 725,
      y = 10,
      width = 75,
      height = 100,
      horizontalAlign = "left"
    )
    d1$defaultColors(
      latticeExtra::theEconomist.theme()$superpose.line$col,
      replace=T
    )
    d1$show("iframe")
  }
)
