Generate plot showing optimal number of components for Repeated Double Cross-Validation

1 | ```
plotcompmvr(mvrdcvobj, ...)
``` |

`mvrdcvobj` |
object from repeated double-CV, see |

`...` |
additional plot arguments |

After running repeated double-CV, this plot helps to decide on the final number of components.

`optcomp` |
optimal number of components |

`compdistrib` |
frequencies for the optimal number of components |
