fAssets (version 4023.85)

plot-similarity: Assets Similarity Plots

Description

Displays plots of similariaies and dissimilarities between data sets of assets.

Usage

assetsDendrogramPlot(x, labels = TRUE, title = TRUE, box = TRUE,
    method = c(dist = "euclidian", clust = "complete"), ...)
    
assetsCorEigenPlot(x, labels = TRUE, title = TRUE, box = TRUE,
    method = c("pearson", "kendall", "spearman"), ...)

Arguments

box

a logical flag, should a box be added around the plot? By default TRUE.

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

[assetsCorgramPlot] -
for the function assetsCorgramPlot a character string, the type of graph used in the lower panel, for the function assetsCorEigenPlot a character string, the method used to compute the correlation matrix.
[assetsTreePlot] -
a character string, the method used to compute the distance matrix, see function dist.

title

a logical flag, should a default title be added? By default TRUE.

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.

...

optional arguments to be passed.
