Predict samples to display on the biplot

This function makes predictions of sample points, variables and means and displays them on the biplot.

Usage

prediction(bp, predict.samples = NULL, predict.means = NULL, which = 1:bp$p)

Arguments

bp

an object of class biplot obtained from preceding function biplot().

predict.samples

a vector specifying which samples to predict.

predict.means

a vector specifying which group means to predict.

which

a vector specifying which variable to do the prediction.

Value

A list object called predict appended to the object of class biplot with the following elements:

samples

a vector of indices of samples which are being predicted.

predict.means

a vector of group names of groups for which the means are being predicted.

which

the vector of indices variables which are being predicted.

predict.mat

the matrix of predicted samples.

predict.means.mat

the matrix of predicted group means.

Examples

biplot(data = iris[,1:4]) |> PCA(group.aes=iris[,5], show.class.means = TRUE) |> 
prediction(141:145,1:3) |> plot()
