In specmine: Metabolomics and Spectral Data Analysis and Mining

Shows a interactive 3D PCA biplot.

1 2	pca_biplot3D(dataset, pca.result, column.class = NULL, pcas = c(1, 2, 3))

`dataset`	list representing the dataset from a metabolomics experiment.
`pca.result`	prcomp object with the PCA results.
`column.class`	metadata's variable.
`pcas`	the three principal components.

  ### Example of a 3D PCA biplot
  library(specmine.datasets)
  data(cachexia)
  pca.result = pca_analysis_dataset(cachexia)
  pca_biplot3D(cachexia, pca.result, "Muscle.loss", pcas = c(1,2,3))
