plot-pairs: Assets Pairs Plot

Description

Display several aspects of correlation bettween pairs of assets.

Usage

assetsPairsPlot(x, labels = TRUE, ...)
assetsCorgramPlot(x, labels = TRUE, 
    method = c("pie", "shade"), ...)
assetsCorTestPlot(x, labels = TRUE, ...)
assetsCorImagePlot(x, labels = TRUE, show = c("cor", "test"), 
    use = c("pearson", "kendall", "spearman"), abbreviate = 3, ...)

Arguments

x

any rectangular time series object which can be converted by the function as.matrix() into a matrix object, e.g. like an object of class timeSeries, data.frame, or mts.

labels

a logical flag, if TRUE then default labels will be used, otherwise the plots will be displayed without labels and the user can add his own labels.

method

a character string, the type of graph used in the lower panel.

show

a character string, what should be pressented, correlations or results from correlation tests?

use

a character string indicating which correlation coefficient or covariance is to be computed. One of "pearson", the default, "kendall", or "spearman".

abbreviate

allows to abbreviate strings to at least abbreviate characters, such that they remain unique, if they were.

...

optional arguments to be passed.

Details

assetsPairsPlot displays pairs of scatterplots of individual assets, assetsCorgramPlot displays correlations between assets, assetsCorTestPlot displays and tests pairwise correlations, assetsCorImagePlot displays an image plot of a correlations.
