In dad: Three-Way / Multigroup Data Analysis Through Densities

Plotting scores of STATIS method (interstructure) analysis

Description

Applies to an object of class "dstatis" (see details of the dstatis.inter function). Plots the scores.

Usage

## S3 method for class 'dstatis'
plot(x, nscore = c(1, 2), sub.title = NULL, color = NULL, fontsize.points = 1.5, ...)

Arguments

x	object of class "dstatis" (returned by dstatis.inter).
nscore	a length 2 numeric vector. The numbers of the score vectors to be plotted. Warning: Its components cannot be greater than the nb.factors argument in the call of the dstatis.inter function.
sub.title	string. Subtitle to be added to each graph.
color	When provided, the colour of the symbols of each group. Can be a vector with length equal to the number of groups.
fontsize.points	Numeric. Expansion of the characters (or symbols) of the groups on the graph. This works as a multiple of par("cex") (see points).
...	optional arguments to plot methods.

Details

Plots the principal scores returned by the dstatis.inter function. A new graphics window is opened for each pair of principal axes defined by the nscore argument.

# Dual STATIS on the covariance matrices
result <- dstatis.inter(rosesf, data.scaled = FALSE, group.name = "rose")
plot(result)
