moveEZ - Animated Biplots

Create animated biplots that enables dynamic visualisation of temporal or sequential changes in multivariate data by animating a single biplot across the levels of a time variable. It builds on objects from the 'biplotEZ' package, Lubbe S, le Roux N, Nienkemper-Swanepoel J, Ganey R, Buys R, Adams Z, Manefeldt P (2024) <doi:10.32614/CRAN.package.biplotEZ>, allowing users to create animated biplots that reveal how both samples and variables evolve over time.

prinsurf - Principal Surface Biplots

Fits principal surfaces (Hastie and Stuetzle, 1989) and constructs smooth, predictive biplot axes for them by gradient flow: each variable's calibrated axis is the steepest-ascent trajectory of its fitted surface coordinate, which is smooth by construction, crosses the variable's contour lines orthogonally, and reduces to the linear principal-component-analysis biplot axis when the surface is flat. Variables whose fitted value has an interior extremum (closed contours) are detected as non-monotone and the axis is withheld in favour of contour-based reading. The implementation is base-R only.

wideRhino - High-Dimensional Methods via Generalised Singular Decomposition

Construct a Canonical Variate Analysis Biplot via the Generalised Singular Value Decomposition, for cases when the number of samples is less than the number of variables. For more information on these biplots, see Ganey, R., & Gardner-Lubbe, S. (2026) <doi:10.1007/s10260-025-00831-y>.
