screeplot.mvPCA {MNM}

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.
