R Documentation

Plotting Method for a Principal Component Object of Type mvPCA

Description

Creates a screeplot for an object of class mvPCA. Works analogously to a normal screeplot for a classical principal component analysis. Here however the y-axis gives the proportion of the variation explained by the components.

Usage

## S3 method for class 'mvPCA'
plot(x, main = deparse(substitute(x)), ...)
## S3 method for class 'mvPCA'
screeplot(x, npcs = min(10, length(x$EigenV)), 
          type = c("barplot", "lines"), 
          main = deparse(substitute(x)), ...)

Arguments

`x`	an object to type `mvPCA`.
`npcs`	the number of components to be plotted.
`type`	the type of plot.
`main`	title of the plot.
`...`	other graphical parameters passed to or from other methods.

Value

A screeplot.

Examples

IRIS <- iris[,1:4]
iris.pca <- mvPCA(IRIS, "sign", "i")
plot(iris.pca, type="lines")
