classification biplot — classification.biplot • biplotEZ

Performs calculations for a classification biplot.

Usage

# S3 method for class 'biplot'
classification(
  bp,
  Pmat,
  dim.biplot = c(2, 1, 3),
  e.vects = 1:ncol(bp$X),
  group.aes = NULL,
  axes = "regression",
  col = ez.col,
  opacity = 0.4,
  borders = FALSE
)

Arguments

bp: an object of class biplot obtained from preceding function biplot().
Pmat: a matrix containing the posterior probability for the classes
dim.biplot: dimension of the biplot. Only values 1, 2 and 3 are accepted, with default 2.
e.vects: which eigenvectors (principal components) to extract, with default 1:dim.biplot.
group.aes: vector of the same length as the number of rows in the data matrix for differentiated aesthetics for samples.
axes: type of axes, defaults to "regression"
col: colour of the classification regions
opacity: opacity of classification regions
borders: logical, indicating whether borders should be added to classification regions

Value

an object of class biplot.
