Z	the matrix of coordinates of the samples
group.aes	vector of the same length as the number of rows in the data matrix for differentiated aesthetics for samples.
show.group.means	logical, indicating whether group means should be plotted in the biplot.
axes	the type of axes to be fitted to the biplot. Options are 'regression' for linear regression axes (default) and 'splines' for B-spline axes.

Value
