Does the analysis of a series of pairs of ecological tables. This function uses Partial Triadic Analysis (pta) and ktab.match2ktabs to do the computations.

`KTX` |
an objet of class ktab |

`KTY` |
an objet of class ktab |

`scannf` |
a logical value indicating whether the eigenvalues bar plot should be displayed |

This function takes 2 ktabs and crosses each pair of tables of these ktabs with the function ktab.match2ktabs. It then does a partial triadic analysis on this new ktab with pta.

a list of class ktab, subclass kcoinertia. See ktab

IMPORTANT : KTX and KTY must have the same k-tables structure, the same number of columns, and the same column weights.
