plot.ics: Scatterplot for a ICS Object

In ICS: Tools for Exploring Multivariate Data via ICS/ICA

Scatterplot for a ICS Object

Description

Scatterplot matrix for an ics object.

Usage

## S4 method for signature 'ics,missing'
plot(x, index = NULL, ...)

Arguments

x	object of class ics
index	index vector of which components should be plotted. See details for further information
...	other arguments for plot

Details

If no index vector is given the function plots the full scatterplots matrix only if there are less than seven components. Otherwise the three first and three last components will be plotted. This is because the components with extreme kurtosis are the most interesting ones.

Examples

    set.seed(123456)
    X1 <- rmvnorm(250, rep(0,8), diag(c(rep(1,6),0.04,0.04)))
    X2 <- rmvnorm(50, c(rep(0,6),2,0), diag(c(rep(1,6),0.04,0.04)))
    X3 <- rmvnorm(200, c(rep(0,7),2), diag(c(rep(1,6),0.04,0.04)))

    X.comps <- rbind(X1,X2,X3)
    A <- matrix(rnorm(64),nrow=8)
    X <- X.comps %*% t(A)

    ics.X.1 <- ics(X)
    plot(ics.X.1)
    plot(ics.X.1,index=1:8)
    rm(.Random.seed)
