Description Usage Arguments Value Author(s) Examples

Takes in a set of predictor variables and a set of response variables and produces a PLS biplot.

1 2 | ```
PLS.biplot(X, Y, algorithm = NULL, ax.tickvec.X = NULL,
ax.tickvec.Y = NULL, ...)
``` |

`X` |
A (NxP) predictor matrix |

`Y` |
A (NxM) response matrix |

`algorithm` |
Any of the PLS algorithms ("mod.NIPALS", "mod.KernelPLS_R", "mod.KernelPLS_L", "mod.SIMPLS") |

`ax.tickvec.X` |
tick marker length for each X-variable axis in the PLS biplot |

`ax.tickvec.Y` |
tick marker length for each Y-variable axis in the PLS biplot |

`...` |
Other arguments. Currently ignored |
