The function plotArrow() visualises the agreement between paired datasets by mapping sample positions in their respective component spaces. The arrow tail represents the sample in one dataset, and the tip represents it in another, so shorter arrows indicate stronger agreement. In rCCA they highlight relationships between canonical variates, while in DIABLO they extend to multiple datasets.
