dimcontrib | R Documentation |

Identifies the categories and individuals that contribute the most to each dimension obtained by a Multiple Correspondence Analysis. It allows to analyze variants of MCA, such as 'specific' MCA or 'class specific' MCA.

dimcontrib(resmca, dim = c(1,2), best = TRUE)

`resmca` |
object of class |

`dim` |
dimensions to describe (default is c(1,2)) |

`best` |
if FALSE, displays all the categories; if TRUE (default), displays only categories and individuals with contributions higher than average |

Contributions are sorted and assigned a positive or negative sign according to the corresponding categories or individuals' coordinates, so as to facilitate interpretation.

Returns a list:

`var` |
a list of categories' contributions to axes |

`ind` |
a list of individuals' contributions to axes |
