longitudinalData (version 2.3)

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

Description

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

Usage

ordered(x,...)

Arguments

x

[ListPartition]: Object whose Partition should be sort.

...

Note used, for S4 compatibility only.

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).

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)
