angles.csa | R Documentation |

Computes the cosines similarities and angles between the dimensions of a CSA and those of a MCA.

angles.csa(rescsa, resmca)

`rescsa` |
object of class |

`resmca` |
object of class |

This function is adapted from `'csa.measures'`

in `'sco.ca'`

package.

A list of matrices:

`cosines` |
Cosine similarities |

`angles` |
