Hi,

I am running a FAMD and then a HCPC on the result, stored in res.hcpc. I am interested in getting the below values out of the "by" class

> res.hcpc$desc.ind

$para

Cluster: 1

25 30 42 88 97

0.7286901 1.4680486 1.6680311 1.7143005 1.8690026

------------------------------------------------------------------------------------------------------------------------------------

Cluster: 2

87 24 17 37 22

0.5039163 0.7346655 0.8302469 0.8302469 0.8447145

------------------------------------------------------------------------------------------------------------------------------------

Cluster: 3

19 60 92 9 13

1.425906 1.425906 1.425906 1.483826 1.483826

------------------------------------------------------------------------------------------------------------------------------------

$dist

65 7 31 70 35

5.885309 5.885309 5.724629 5.724629 5.573382

into a usable data.frame e,g.

Measure Cluster Record Value

para 1 25 0.7286901

para 1 30 1.4680486

..

dist 4 65 5.885309

Thanks

The object "desc.ind$para" gives the individual(s) the clostest to the centre of gravity of a cluster (and it gives the distance between each individual and the centre of gravity of the cluster).

The object "desc.ind$dist" gives the individuals the farest from the centres of gravity of the other clusters (an individual that couldn't be in the other clusters because very far from the other cluster and in this way it is a specific individual). The distance to the centre of gravity of the closest cluster is given.

Hi Francois,

Thanks for your explanation of $para and $dist. I am familiar with the terms. If you look at the end of my question, I actually want to export these values in a usable way and I don't know how to do that. It is in a "by" class which as far as I understand is a list of named vectors or similar.
