screeplot.mvPCA {MNM} | R Documentation |
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.
## 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)), ...)
x |

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. |
A screeplot.
