update {rEMM}

Update a TRACDS temporal structure with new state assignements

Description

Add a sequence of new state assignments to a TRACDS object.

Usage

## S4 method for signature 'TRACDS'
update(object, newdata, verbose=FALSE, ...)
reset(x)
compact(x)

Arguments

x, object

a TRACDS object. Note that this function changes the original object!

newdata

a vector with a state assignemnt sequence (typically produced by clustering).

verbose

logical; verbose output?

...

further arguments.

Details

update() adds a new state assignemnt sequenc to the TRACDS object by increasing the transition counts and, if needed, creating new states.

reset() resets the current state to NA for reading in a new sequence. An NA in newdata also resets the current state.

compact() reduces the size (memory) used to store the temporal transition matrix.

Value

A reference to the changed TRACDS object with the data added. Note: EMM objects store all variable data in an environment which enables us to update partial data without copying the whole object. Assignment will not create a copy! Use the provided method copy().

## create an empty TRACDS object
tracds <- TRACDS()
tracds

## update with an cluster assignment sequence
update(tracds, c(1,2,5,5,2))
tracds
