screeplot.mvPCA: 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)), ...)

Value

• A screeplot.
