Plot Function for geomorph
# S3 method for pls
plot(x, label = NULL, ...)If shapes = TRUE, function returns a list containing the shape coordinates of the extreme ends of axis1 and axis2 if 3D arrays were originally provided for each
plot object (from phylo.integration or two.b.pls)
Optional vector to label points
other arguments passed to plot. The function returns values that can be used with
picknplot.shape (in a limited capacity). In most cases, greater
flexibility can be attained with using plotRefToTarget and shape.predictor.
