longitudinalData (version 2.4.7)

ordered(ListPartition): ~ Function: ordered(ListPartition) ~

Description

Sort the Partition of a ListPartition according to a quality criterion.

Usage

ordered(x,...)

Value

This function change internaly the order of the fields c2,

c3, ... c26 of an object. In addition, it return the permutation matrix (the matrix use to re-ordered the ci).

Arguments

x

[ListPartition]: Object whose Partition should be sort.

...

Note used, for S4 compatibility only.

Details

Sort the Partition of a ListPartition for each list (sort the 'c2' list, the 'c3' list,...) according to a quality criterion. The criterion used to sort is the one in the field criterionActif.

Examples

##############
### Preparing data
data(artificialLongData)
traj <- as.matrix(artificialLongData[,-1])

### Some clustering
part2 <- partition(rep(c("A","B"),time=100),traj)
part3 <- partition(rep(c("A","B","C","A"),time=50),traj)
part3b <- partition(rep(c("A","B","C","B"),time=50),traj)
part4 <- partition(rep(c("A","B","C","D"),time=50),traj)
